Simple Expression

Simple expressions are not as flexible as normal scripts, but they are compiled for a very efficient execution.
Following operators are available:
| randomGen | a random value from 0 to a |
| a factor [x,y] | a<=x: 0 a>=y: 1 x<=a<=y: ratio between x and y Note: works fine even for x>y (calculated as 1-a factor [y,x]) |
| a interpolate [xFrom,xTo,resFrom,resTo] | Introduced in ArmA 2 1.05. interpolate result based on input value.
Equivalent to x factor [xFrom,xTo] * (resTo-resFrom) + resFrom |
| 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 |
| a / b | see a/b (for A3, not sure if others) |
| abs a | see abs (A3 post 1.66 update only) |
Description: a,b can be any simple expression. x,y can be a constant expression only (i.e. expression with a type Number).
