C code Float to Int (format print string) convert decimals

Question

I'm trying to write a format print string that outputs this number (float 0.2005) as a percent with only 2 decimals (20.05%).

Use %% to output the % sign itself, and use .2 to control precision.

float f = 0.2005;
printf("%.2f%%\n", f * 100);

Spontaneously, I would do this:

float a = 0.2005;
printf("%.2f%%\n", a * 100.0);

Code :

main()
{
    float a = 0.2005;
    float b = a * 100;
    printf("%.2f\n",b);
}
