ceil, floor, isinf, isnan, trunc should now return a value of the same type as for the math module. Does not work, though (tests fail).
Working new (in umath) ceil, floor, isinf, isnan, trunc (their result has the same type as in math.*).
Added test for the new functions in umath.locally_cst_funcs.
