random() but as a float? - Celson - 15.03.2011

Is there a function out there that creates a random number with decimals?

Re: random() but as a float? - pawn_ - 15.03.2011

pawn Code:

float(random(...))

What is Dp? Is it the number count after the dot?

You can use that as:

pawn Code:

new Float:rand = frandom(5.5); // Any float from 0.0 to 5.5 (up to 4 dp).
new Float:rand = frandom(5.5, -5.5); // Any float from -5.5 to 5.5 (up to 4 dp).
new Float:rand = frandom(5.5, 0.0, 1); // Any float from 0.0 to 5.5 (up to 1 dp).
new Float:rand = frandom(5.5, -5.5, 1); // Any float from -5.5 to 5.5 (up to 1 dp).

i get tag mismatch on this line
return float(random(imax - imin) + imin) / mul;
:/

Try changing the header of the method from:

frandom(Float:max, Float:min = 0.0, dp = 4)

to:

Float:frandom(Float:max, Float:min = 0.0, dp = 4)
