DIAGNOSTICS
Functions in the Math Library (3M) may return the conventional
values 0 or HUGE (the largest single-precision floating-point
number) when the function is undefined for the given arguments �
or when the value is not representable. In these cases, the external
variable errno (see intra (2)) is set to the value EDOM or
ERANGE. As many of the FORTRAN intrinsic functions use the
routines found in the Math Library, the same conventions apply.
