--------------------------------+-------------------------------------------
There are special formulas to apply for quotients of gamma values, since
those quotients can be pretty reasonable even though the numerator and
denominator are too big, for example:
{{{
sage: binomial(float(1000),float(1001))
nan
sage: binomial(1000,1001)
0
}}}
and:
{{{
sage: binomial(float(1001),float(1000))
nan
sage: binomial(1001,1000)
1001
}}}
