Mantis#1451. Thank you kindly, Mikem for a patch that addresses:
LSL scripts in which a float type is cast to a string or a string type is cast to a float do not compile. When the script is translated from LSL to C#, the LSL float type is translated into double. There is no string <-> double cast in C#, so compilation fails. There is a LSLFloat type, however it seems unfinished and is not used. I am attaching a patch that implements the LSLFloat type. I have also added two methods to the LSLString type to facilitate float <-> string casts.
