Is it reasonable to assume most modern compilers will see float**2 and replace it with float*float? I'm trying to improve the readability of someone else's code, without sacrificing performance, although I'm sure it's been quite some time since the code has been profiled on current hardware.
just to clarify, the actual variable is a multidimensional array with a longer name, and is being indexed/sliced, so typing the equivalent of float*float is much longer than typing the exponentiation.
Yes, all high quallty Fortran compilers I've seen in the last decade are expanding and optimizing **2 (some will do it even with the decimal point implying a real data type exponent).
You could try a limited test, simply assure that no exponentiation function call is introduced when you run nm on the .o file.
