Use proper format specification fields of printf [^]. For instance

float x = 1.237f;
printf("x=%8.2f\n", x);

As you may observe (the output is x = 1.24), the value is rounded.

use sprintf to format your floating point number into a string that has the format you desire. I assume you're really using C, and not C# ?
