Fsine() is a fast 360┬░ Sinus function. Input parameter is an angle (0-359) in degrees. The result is a Single precision value between -1 and +1.

Syntax: result = Fsine( Expression ) Fsine does a 20x faster conversion that the equivalent floating point Sinus/Cosine calculation because it uses a lookup table. The function accepts whole numbers only.
