How to express keeping two decimal places in C language

In C language, the representation method is "%.2lf" and the syntax format is "printf("%.2lf,%.2lf\n", element)". "%.2lf" In the "printf()" statement, the entire integer part is output, and the decimal part is output with 2 digits. If it is less than two digits, 0 is added at the end, and if it is more than two digits, it is truncated to two digits.

float a,b; 
a=1.123456; 
b=2.324855; 
printf("%lf,%lf\n",a,b); 
return 0;
