Do note that this can SOMETIMES return MaxVal; so the … WebJun 8, 2015 · I'm learning c++ and I'm trying to generate a random float and seem to be having some difficulties. I start by making a random int(), newRandom, between -100 and 100, then I take that newRandom and turn it into a random float, rand_X, between -1.0 and 1.0. The only caveat is I don't want rand_X to be between -0.2 and 0.2, in other words,

It doesn't affect any of the particles because you are disabling depth test when you render them, but when you render the plane, depth test is enabled, and since the depth buffer has not been cleared it has a spaz and doesn't render the plane. Do. WebFast Float Random Numbers. a small and fast implementation for random float numbers in the range [-1,1], usable as white noise oscillator. compared to the naive usage of the rand () function it gives a speedup factor of 9-10. compared to a direct implementation of the rand () function (visual studio implementation) it still gives a speedup by a ... smalls confectionary forfar

The most simple (and actually most random) function is to just write the data of a random int into a float, thus. int tmp = rand(); float f = (float)*((float*)&tmp); note that if you do float f = (float)rand(); it will convert the integer into a float (thus 10 will become 10.0).
