Series benchtests: Add float version of math functions to bench-math | expand

Commit Message

Sunil Pandey Oct. 29, 2021, 5:19 p.m. UTC 
Add atanhf function to bench-math and copy atanhf-inputs to benchtests.
Motivation for this patch is to prepare for upcoming libmvec new
functions.  Float and double version of libmvec functions stays
together.

atanhf-inputs file generated from atanh-inputs file using following
scaling formula:

f = d * (FLT_MAX/DBL_MAX)

Where d is input(double) and f is output(float).  If scaled float value
is duplicate in new input file, nextafterf() function used to find next
float value, ensuring no duplicates.

this seems wrong.
