Apologies for the delay, I am a carer or babysitter presently for my mother or grandchild and dogs.
However @ Corona688...

Well tested your 'BASH' version with just one edge case and there will be quite a few...
Note with your original, 2.0 - 3.14159 = -1.141, not what is shown.
Then I just did one edge case, I changed '2.0' to '0.073' and...
NOTE: Not related to either your or my versions; I have manually found many edgecases. Python was a godsend for this task.

3.14159 * 2.0 = 6.282
3.14159 / 2.0 = 1.570
2.0 - 3.14159 = 1.141		# WRONG! -1.141
3.14159 - 2.0 = 1.141
3.14159 + 2.0 = 5.141
AMIGA:amiga~/Desktop/Code/Shell> # Just one edge case, change BB to 0.073.
AMIGA:amiga~/Desktop/Code/Shell> ./FPMATH_C688.sh
3.14159 * 0.073 = 0.185
3.14159 / 0.073 = 53.237
0.073 - 3.14159 = 3.082
3.14159 - 0.073 = 3.082
3.14159 + 0.073 = 3.200
AMIGA:amiga~/Desktop/Code/Shell> # Oops, they are all wrong.
AMIGA:amiga~/Desktop/Code/Shell> _

Code:
Google calculator:
3.14159 * 0.073 = 0.229
3.14159 / 0.073 = 43.035
0.073 - 3.14159 = -3.068
3.14159 - 0.073 = 3.068
3.14159 + 0.073 = 3.214

As I said I have learnt a lot about 'dash' and POSIX. Your 'heredoc' code is wonderful.
As above I have found many edge cases.
Also the strange effects closing the gaps to the + or - limits I have set.
I will be back ASAP but family comes first.
