#include <stdio.h> #include <math.h> int main () { float val1, val2, val3, val4; val1 = 1.6; val2 = 1.2; val3 = 2.8; val4 = 2.3; printf ("value1 = %.1lf\n", ceil(val1)); printf ("value2 = %.1lf\n", ceil(val2)); printf ("value3 = %.1lf\n", ceil(val3)); printf ("value4 = %.1lf\n", ceil(val4)); return(0); }
