[PD] expr "copysign" function doesn't seem to work

[Jan Baumgart]

It's spelled "copysig" in expr.
But I couldn't get it to work.

copysig in expr only takes one argument, whereas the c math function 
takes two arguments:
float copysignf(float x, float y);

It returns the absolute value of x with the sign of y.

Smells like a bug to me...

cheers,
Jan
