 Two families of "safe casting" functions are added to ''ext/standard'', ''try_''* and ''to_''*, for ''int'', ''float'' and ''string''. These functions validate their input to ensure data is not lost with the cast (thus the cast can be considered safe), instead of casting blindly. If the input fails to validate, the ''to_''* functions throw a ''CastException'', while the ''try_''* functions return NULL. If validation succeeds, the converted result is returned. Two families of "safe casting" functions are added to ''ext/standard'', ''try_''* and ''to_''*, for ''int'', ''float'' and ''string''.
