How to express two digits after decimal point in C language

In C language, you can obtain the two digits after the decimal point of a floating-point number by following the following steps: Multiply the floating-point number by 100 to turn the decimal part into an integer. Use the / operator to divide a floating point number by 100, rounding off the integer part. Use the % operator to get the decimal part of a floating point number modulo 100.

Take two digits after the decimal point in C language

In C language, you can use the truncated division operation Use the / operator and the modulo operator % to obtain the decimal part of a floating point number.

Steps:

1. Multiply the floating point number by 100 so that its decimal part becomes an integer.
2. Use the / operators to divide a floating point number by 100 and round the integer part.
3. Use the % operator to make the floating point number modulo 100 and get the decimal part.

Sample code:

<code class="c">#include <stdio.h>

int main() {
    float num = 123.456;
    int int_part = num / 100;
    int dec_part = num % 100;

    printf("小数点后两位数字：%d\n", dec_part);

    return 0;
}</code>

Output:

<code>小数点后两位数字：45</code>
