在整数和浮点数之间转换

#include <stdio.h>

int main (void)
{
    float f1 = 123.125, f2;
    int i1, i2 = -150;
    char c = 'a';

    // floating to integer conversion
    i1 = f1;//
    printf (%f assigned to an int procedure %i\n, f1, i1);

    // integer to floating conversion
    f1 = i2;
    printf (%i assigned to a float procedure %f\n, i2, f1);

    // integer divided by integer
    f1 = i2 / 100;
    printf (%i divided by 100 produces %f\n, i2, f1);

    // integer divided by float
    f2 = i2 / 100.0;
    printf (%i divided by 100.0 produces %f\n, i2, f2);

    // type cast operator
    f2 = (float) i2 / 100;
    printf ((float) %i divided by 100 produces %f\n, i2, f2);

    return 0;
}
