  • Your only real problem is that %d format is for printing integers and the values you want to print are not integral. You should be using %f, %e, or %g instead of %g if you want the fractional part printed out. If you do not want the fractional part printed out, then use the format you have now, but pass fix(a) or round(a) instead of a (depending whether you want truncation or rounding)
