#389 closed proposed feature (fixed)

transfer denominator() and numerator() from poly.lib to the Singular kernel

Description

denominator() und numerator() are currently procs in poly.lib. The code looks like this: 

proc denominator(number n)
{
  poly p = cleardenom(n+var(1));
  return (number(coeffs(p,var(1))[2,1]));
}

This is OK, but I expect that kernel commands could be much faster. Note that these procedures are used extensively by modStd().
