Floating-point classification type used by fp_classify
,
for example, indicating the value is normal, i.e., it is not zero, NaN, infinite,
nor subnormal.
Include
<math.h>
Floating-point classification type used by fp_classify
,
for example, indicating the value is subnormal. Subnormal values are non-zero
values, with magnitude smaller than the smallest normal value. The normalisation
process shifts leading zeros out of the significand and decreases the exponent, but
where this process would cause the exponent to become smaller than its smallest
representable value, the leading zeros are permitted and the value becomes
subnormal, or denormalised.

This macro has the value 1 and is usable with math_errhandling
to
determine the implementation response to a domain error.
Include
<math.h>
Value
The value 1.
This macro has the value 2 and is usable with math_errhandling
to
determine the implementation response to a domain error.
Include
<math.h>
Value
The value 2.
This is a value that can be used to determine if errno
will be set
or an exception will be raised on a domain error. If the value of
math_errhandling & MATH_ERRNO
is true, then
errno
will be updated with the appropriate error number. If the
value of math_errhandling & MATH_ERREXCEPT
is true, then an
invalid floating-point exception will be raised when a domain error is
encountered.
Include

Value
The value 1.

value.
