- new functions: Sin( rad ), Cos( rad ), Tan( rad ), Log( x ), Log10( x ), Sqrt( x )
- new predefined variables: PI (3.1415...), PHI (1.618...), EULERT (e = 2.7182...)
- new operator ^ (power), e.g. 3^2 = 9. Same priority as *, /, %, i.e. 2*2^2 = (2*2)^2 = 16!
- removed debug message in Split
- bugfix in numerical operators: If one of the parameters was no float value, both values were converted to integer, e.g. 2 * 2.6 = 6 (2.6 was round to 3)
