A domain error occurs if the value of a parameter input to a function is outside the domain
over which the mathematical function is defined. In this case, the value of EDOM is set in
errno. The function return value depends on the implementation.
A range error occurs if the result of a function cannot be represented as a float value. In this
case, the value of ERANGE is set in errno. If the result overflows, the function returns the
value of HUGE_VAL, with the same sign as the correct value of the function. If the result
underflows, 0 is returned as the return value.
dangerous to use the resultant value directly. The value of errno should always be checked
before using the result in such cases.
Example:
x=asinf(a);
if (errno==EDOM)
else
