Here's a C variation:

#include <stdlib.h>
#include <time.h>
#include <stdio.h>

float Randf(float min, float max)
{
	return (float)(rand() / (RAND_MAX / (max - min) + 1) + min);
}

int main()
{
	int i;
	srand((unsigned)time(NULL));
	for (i=0; i<10 ;i++)
		printf("%f\n",Randf(-.5, .5));
	getch();
	return 0;
}
