The floating point library only provides basic arithmetic, square root and natural logarithm and exponential. The trigonometric functions are implemented differently on each.

I believe that Free42 Decimal has moved to the Intel decimal library which is different again. It is much faster than the 34S's code but it is also much larger -- there are quite a few large lookup tables and it uses binary arithmetic and transcendental functions to get initial approximations for decimal results. In effect, you end up with two mathematics libraries.
