This is the C source, if you haven’t looked at it yet.
BigDecimal_sqrt(VALUE self, VALUE nFig)
Real *c, *a;
S_INT mx, n;
mx = a->Prec *(VpBaseFig() + 1);
n = GetPositiveInt(nFig) + VpDblFig() + 1;
if(mx <= n) mx = n;
I don’t fully understand what’s going on with it, because my C is
pretty weak, but hopefully this will provide some insight from
