It might be nice to have a MPFR contribution or based on GMP or something.
There has been recent interest in allowing our number tower to be expanded for
such use cases with the basic math o
The log1+ word uses flog1p and works well when numbers are small.
The expm1 is provided as well, but not as a call the fexpm1:

It’s a one line change to add fexpm1 plus tests to make sure it works if you’d

Dear Sir,
The function e^x - 1 , called fexpm1, is provided for in both C libm and x87
instructions, just like it's counterpart log1p (ln(1+x)). While flog1+ is
provided in factor vocabulary math.libm, expm1 is missing. Both functions are
useful when x is small compared to 1.
Kindly provide ex
Dear Sir,
Continuing about fexpm1 and flog1p, kindly note that in vocabulary
math.functions the definition of log1+ given as 1 + log, defeats the purpose of
giving flog1p in that 1 + log will always give inaccurate values when x <<1.
This definition of log1+ should be removed from the vocabular
Dear Sir,
Does factor support arbitrary precision floats, such as provided by libmpfr or
libBF?
