Hi all,

I understand that unrealscript will coerse float values to int if you do something like :

var int i;
var float f;

f = 5.7;
i = f;

However what arrived in i? Does it round up, round down, or just ignore the fractional part?
Are there any convenient functions that can force the issue?

Cheers.

Phill.

It truncate. For round, you can add 0.5 before cast to positive numbers and subtract 0.5 for negative.

Code: Select all

	fv = 5.7;
	return BadParameters("f =" @ fv @ "(int)f =" @ int(fv) @ "(int)-f =" @ int(-fv)
		@ "(int)(f + 0.5) =" @ int(fv + 0.5) @ "(int)(-f - 0.5) =" @ int(-fv - 0.5));

Code: Select all

---------------------------
Warning
---------------------------
f = 5.700000 (int)f = 5 (int)-f = -5 (int)(f + 0.5) = 6 (int)(-f - 0.5) = -6
---------------------------
ОК

Also, keep in mind unreal script has float to int cast bugs...
