float random - RedGun2015 - 29.06.2018

Hello, i'm working on a experience level with percent. And i need a float random function, like:

randomFloat(min,max);
to be something like (random((max) - (min)) + (min)) - this is only for integer but I want for float, I know that random is not for float, but you might now a function to get random float from min and max. ex: randomFloat(30.5, 60.10) to get a random float value from this two..

But I really don't know how to do that.
I've searched on forum, but i didn't find what i need..

You are working on random float spawns?

Nope, exp for next level, ex: you need 253.53 percent for level 5 (you have 53.01).
And I want to give random experience (percent) when doing a job, doing missions or receiving a payday.

I didn't see something like this before.
Check all random codes on sa-mp wiki: https://sampwiki.blast.hk/wiki/Random

Why do you bother with floating-point numbers? Experience can be an integer and do your coding much easier.

Anyway, based on your example you can still generate a random number as integer (like the way you showed, it is correct) and then convert to float.

I checked but I did not find anything of this kind.

Are you sure?
