How to disable minus sign for zero value

[pierangelo]

using the IFORT compiler the option 'Floating point' 'Enable IEEE Minus Zero Support' 'No' works correctly: only the value 0.0 is allowed
Using the IFX compiler it seems that the indicated option does not work in fact in the code I also have the value -0.0 and the test a.ne.0. gives the result .false. when a = -0.0

try /assume:nominus0 compiler option but the testing a real to equal zero is not robust code, you need a tolerance.
