560/* Typecasting
561
562LSL is statically typed, so stored values are not converted, only the values used in expressions are.
563Lua is dynamically typed, so stored values are changed (sometimes I think).
564
565LSL implicitly typecasts - There is a shitload of QUIRKs about this. Apparently some don't work anyway.
566 integer -> float (Says in lslwiki that precision is never lost, which is bullshit, since they are both 32 bit. Would be true if the float is 64 bit. Lua suggest to use 64 bit floats to emulate 32 bit integers.)
567 string -> key
568 Some functions need help with this or the other way around.
569 string -> vector (Maybe, should test that.)
570 vector -> string (Maybe, should test that.)
571 Also happens when getting stuff from lists.
572
573Explicit type casting -
574 string -> integer
575 Leading spaces are ignored, as are any characters after the run of digits.
576 All other strings convert to 0.
577 Which means "" and " " convert to 0.
578 Strings in hexadecimal format will work.
579 keys <-> string
580 No other typecasting can be done with keys.
581 float -> string
582 You get a bunch of trailing 0s.
583
584QUIRK - I have seen cases where a double explicit typecast was needed in SL, but was considered to be invalid syntax in OS.
585
586Any binary operation involving a float and an integer implicitly casts the integer to float.
587
588A boolean operation deals with TRUE (1) and FALSE (0). Any non zero value is a TRUE (generally sigh).
589Bitwise operations only apply to integers. The shifts are arithmatic, not logical. Right shifted bits are dropped, left shifts the sign bit.
590
591integer = integer0 % integer1; // Apparently only applies to integers, but works fine on floats in OS.
592string = string0 + string1; // Concatenation.
593list = list0 + list1; // Concatenation. Also works if either is not a list, it's promoted to a list first.
594list = (list=[]) + list + ["new_item"]; // Voodoo needed for old LSL, works in Mono but not needed, does not work in OS. Works for strings to.
595bool = list == != int // Only compares the lengths, probably applies to the other conditionals to.
596vector = vector0 + vector1; // Add elements together.
597vector = vector0 - vector1; // Subtract elements of vector1 from elements of vector0.
598float = vector0 * vector1; // A dot product of the vectors.
599vector = vector0 % vector1; // A cross product of the vectors.
600vector = vector * float; // Scale the vector, works the other way around I think. Works for integer to, but it will end up being cast to float.
601vector = vector / float; // Scale the vector, works the other way around I think. Works for integer to, but it will end up being cast to float.
602vector = vector * rotation; // Rotate the vector by the rotation. Other way around wont compile.
603vector = vector / rotation; // Rotate the vector by the rotation, in the opposite direction. Other way around wont compile.
604rotation = llGetRot() * rotation; // Rotate an object around the global axis.
605rotation = rotation * llGetLocalRot(); // Rotate an object around the local axis.
606rotation = rotation0 * rotation1; // Add two rotations, so the result is as if you applied each rotation one after the other.
607 // Division rotates in the opposite direction.
608rotation = rotation0 + rotation1; // Similar to vector, but it's a meaningless thing as far as rotations go.
609rotation = rotation0 - rotation1; // Similar to vector, but it's a meaningless thing as far as rotations go.
610
611A boolean operator results in a boolean value. (any types)
612A comparison operator results in a boolean value. (any types)
613A bitwise operator results in an integer value. (intInt or int)
614A dot product operator results in a float value. (vector * vector)
615A vectorFloat results in a vector value.

559/* Typecasting
560
561LSL is statically typed, so stored values are not converted, only the values used in expressions are.
562Lua is dynamically typed, so stored values are changed (sometimes I think).
563
564LSL implicitly typecasts - There is a shitload of QUIRKs about this. Apparently some don't work anyway.
565 integer -> float (Says in lslwiki that precision is never lost, which is bullshit, since they are both 32 bit. Would be true if the float is 64 bit. Lua suggest to use 64 bit floats to emulate 32 bit integers.)
566 string -> key
567 Some functions need help with this or the other way around.
568 string -> vector (Maybe, should test that.)
569 vector -> string (Maybe, should test that.)
570 Also happens when getting stuff from lists.
571
572Explicit type casting -
573 string -> integer
574 Leading spaces are ignored, as are any characters after the run of digits.
575 All other strings convert to 0.
576 Which means "" and " " convert to 0.
577 Strings in hexadecimal format will work.
578 keys <-> string
579 No other typecasting can be done with keys.
580 float -> string
581 You get a bunch of trailing 0s.
582
583QUIRK - I have seen cases where a double explicit typecast was needed in SL, but was considered to be invalid syntax in OS.
584
585Any binary operation involving a float and an integer implicitly casts the integer to float.
586
587A boolean operation deals with TRUE (1) and FALSE (0). Any non zero value is a TRUE (generally sigh).
588Bitwise operations only apply to integers. The shifts are arithmatic, not logical. Right shifted bits are dropped, left shifts the sign bit.
589
590integer = integer0 % integer1; // Apparently only applies to integers, but works fine on floats in OS.
591string = string0 + string1; // Concatenation.
592list = list0 + list1; // Concatenation. Also works if either is not a list, it's promoted to a list first.
593list = (list=[]) + list + ["new_item"]; // Voodoo needed for old LSL, works in Mono but not needed, does not work in OS. Works for strings to.
594bool = list == != int // Only compares the lengths, probably applies to the other conditionals to.
595vector = vector0 + vector1; // Add elements together.
596vector = vector0 - vector1; // Subtract elements of vector1 from elements of vector0.
597float = vector0 * vector1; // A dot product of the vectors.
598vector = vector0 % vector1; // A cross product of the vectors.
599vector = vector * float; // Scale the vector, works the other way around I think. Works for integer to, but it will end up being cast to float.
600vector = vector / float; // Scale the vector, works the other way around I think. Works for integer to, but it will end up being cast to float.
601vector = vector * rotation; // Rotate the vector by the rotation. Other way around wont compile.
602vector = vector / rotation; // Rotate the vector by the rotation, in the opposite direction. Other way around wont compile.
603rotation = llGetRot() * rotation; // Rotate an object around the global axis.
604rotation = rotation * llGetLocalRot(); // Rotate an object around the local axis.
605rotation = rotation0 * rotation1; // Add two rotations, so the result is as if you applied each rotation one after the other.
606 // Division rotates in the opposite direction.
607rotation = rotation0 + rotation1; // Similar to vector, but it's a meaningless thing as far as rotations go.
608rotation = rotation0 - rotation1; // Similar to vector, but it's a meaningless thing as far as rotations go.
609
610A boolean operator results in a boolean value. (any types)
611A comparison operator results in a boolean value. (any types)
612A bitwise operator results in an integer value. (intInt or int)
613A dot product operator results in a float value. (vector * vector)
614A vectorFloat results in a vector value.
