I'm beginner to programming in general.
Say I have:
int x = 80;
int y = 6;
double average;
average = x / y;
printf("%f", average);
when i do this it outputs 13.000000 but i need it to output 13.33333
how would i go about doing this? i cannot change x or y to a double variable for it messes up other parts of my program. thanks in advance.
Here, "x / y" is casted to double *after* the calculation x/y has been made.
Explicitly casting to double before the calculation:
will get you the expected floating-point result.Code:average = ((double) x) / ((double) y);
Consider this post signed
You would 'Type Cast' x or y. It will not change x or y.
You only need to typecast the first one:
@OP - use CODE tags in the future for posting.Code:double average = (double) x / y;
Well you can actually cast either one. As long as one of the operands is a double then the other must also be promoted to a double.Originally Posted by memcpy
