Generate random float between two floats

Question

I know this is a rather simple question, but I\'m just not too good at maths.

I know how to generate a random float between 0 and 1:

float random = ((flo         


        

Answer 1

float RandomFloat(float a, float b) {
    float random = ((float) rand()) / (float) RAND_MAX;
    float diff = b - a;
    float r = random * diff;
    return a + r;
}

This works by returning a plus something, where something is between 0 and b-a which makes the end result lie in between a and b.
