I\'m writing a small bignum library for a homework project. I am to implement Karatsuba multiplication, but before that I would like to write a naive multiplication routine.
If I do the following: int c0 = CHAR_MAX; //8 bit int c1 = CHAR_MAX; //8-bit in开发者_如何转开发t i = c0*c1; //store in 32-bit variable
I have an array called $times. It is a list of small numbers (15,14,11,9,3,2). These will be user submitted and are supposed to be minutes. As PHP time works on seconds, I would like to multiply each
