Simple Expression

Simple expressions are not as flexible as normal scripts, but they are compiled for a very efficient execution.

Folowing operators are available:

randomGen	a random value from 0 to a
a factor [x,y] 0	when a<=x, 1 when a>=y, interpolated in between. Note: works fine even for x>y (calculated as 1-a factor [y,x])
a min b	see min
a max b	see max
a - b	see a-b
a + b	see a+b
a * b	see a*b

Description: a,b can be any simple expression. x,y can be a constant expression only (i.e. expression with a type Number).
