Constexpr cmath floor of 1 is returning 0

[marcoffee]

boost::math::ccmath::floor(1.0) is returning 0.0 instead of 1.0.
Looks like the issue is here, when it compares the arg with result (which is 1) and returns 0 if the arg >= result.

Hi @marcoffee thanks for your query.

Hi Matt (@mborland) I'm working in this area now. What a coincidence.

I wonder if else if(result > arg) on line 49 and a follow-up default case for exaclty 1 might do the trick?

Or should we check for argument identical to 1?
