Constant: math errors
Include:
Context: Global variable containing an integer value reflecting the type
of math error encountered.
Synopsis: The following errors can be generated by the math routines of
the C run-time library. These errors correspond to the exception
types defined in math.h and returned by the matherr function
when a math error occurs.
DOMAIN
An argument to the function is outside the domain of the
function.
OVERFLOW
The result is too large to be represented in the function's
return type.
PLOSS
A partial loss of significance occurred.
SING
Argument singularity: an argument to the function has an illegal
value (for example, the value 0 is passed to a function that
requires a nonzero value).
TLOSS
A total loss of significance occurred.
UNDERFLOW
The result is too small to be represented. (This condition is
not currently supported.)
