Truncate double data type to integer 1

[taz75]

I need to truncate a double data type and then only work with the "Whole" number part.

ie when the number in question is 18.336 I only need 18.

 

[Denster]

use type casting as below :-

#include <stdio.h>


void main()
{
double s = 18.336;
int f;
f = (int)s;
printf(&quot;%d&quot;,f);
}

This has the effect of chopping off everything after the
decimal point.

You don't even need the cast, just:

double s=18.336;
int f=s;

The decimal portion is silently truncated.
