Generating a random double between a range of values

Question

Im currently having trouble generating random numbers between -32.768 and 32.768. It keeps giving me the same values but with a small change in the decimal field. ex : 27.xx

Answer 1

It seams to be plainly obvious but some of the examples say otherwise... but i thought when you divide 1 int with another you always get an int? and you need to type cast each int to double/float before you divide them.

ie: double r = (68.556* (double)rand()/(double)RAND_MAX - 32.768);

also if you call srand() every time you call rand() you reset the seed which results in similar values returned every time instead of ''random'' ones.
