ceil() in C

ceil() returns the smallest integral value that is not less than its argument. The return type is still double.

Syntax Top ↑

double ceil(double x);

Example 1 Top ↑

#include <math.h>

int main(void) {
    double value = 5.2;

    printf("ceil(5.2): %.1f\\n", ceil(value));
    return 0;
}
