Help with calculating percentage in C
-
Hope no one screams at me but if they do I guess its okay this question is simple its ridiculous but here goes my total number in decimal is 1,621,270,208 the number I am trying to figure out the percent is from is 1,604,667,016 I did this calculation on the web and it came out to 98% the two number the first being total is a int the second unalloc is also a int. the variable percent is a double or float I thought mistaking that percent = unalloc / total woudgive me 0000.98 in percent but I realize that since the quotient is zero percent is 000.000 doing percent = unalloc % total would give the reminder in percent and thus a value of 1604665335.000 I have searched the web I know this is real simple to some of you wonder if you could help thanks in advance

Presumably you're doing something like
int total = 100;
int unalloc = 96;
double percent = unalloc/total;So the problem here is that since unaloc and total are both
int, the calculation is done in integer math, and then promoted to double. What you need to do is to promote either operand to the division to double (or both):double percent = (double)unalloc/total:
Keep Calm and Carry On

double total = 1621270208;
double percentFrom = 1604667016;
double percent = percentFrom / total * 100; -

hey k5054 my comment does not relate to the currently running thread. I just wanted to let you know I keep getting back to some of your replies in topic I have posted quite a while ago. I thought it might be a good idea to let you know I`m haunting those posts.
