Hi!
Sorry, I won't implement this, as FOR loops with floating point variables are a bad idea:
- It is a lot slower, as you have an extra floating-point comparison on each step.
- Is nor predictable, as floating-point math is not exact. In your example above you will loop 59, 60 or 61 times depending on the floating-point implementation and rounding.
Correct way to implement above loop is:
th%=-PI%
FOR i=0 TO 60
'..... do something...
th% = th% + PI%/20
NEXT
Have Fun!
