Pyccelisation of a cmath function

[tomcaruso]

Describe the bug

Pyccel does not support the cmath library.

To Reproduce

Try to pyccelise the following file :

from cmath import cosh
def function(a:'complex'):
    a1 = cosh(a)
    return(a1)

Error details

Provide the generated code, or the error message:

error [semantic]: cmath_test_function.py [1]| Module cmath is not currently supported by pyccel 

Expected behavior

I suppose that cmath library being similar to the math one, Pyccel should be able to call it no ?

Language

Fortran

You are correct this should be fairly easy to add by following the example shown by the math library. The cmath functions are available in the complex.h header file in C (https://en.wikibooks.org/wiki/C_Programming/complex.h) and should be built-in in Fortran
