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 tanhf function to bench-math and copy tanhf-inputs to benchtests.
Motivation for this patch is to prepare for upcoming libmvec new
functions.  Float and double version of libmvec functions stays
together.

tanhf-inputs file generated from tanh-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.

Dear Sunil,

out of the 200 inputs, 28 yield tanh(x)=1 or -1, and 52 yield tanh(x)=x,
thus only 120 exercise the "real cases".

Also maybe you could enlarge the file to 1000 inputs?

Paul
