The floating-point number @var{x} is ``Not a Number'' (@pxref{Infinity

@item FP_INFINITE
@standards{C99, math.h}
The value of @var{x} is either plus or minus infinity (@pxref{Infinity
and NaN})
@item FP_ZERO
@standards{C99, math.h}
The value of @var{x} is zero. In floating-point formats like @w{IEEE
754}, where zero can be signed, this value is also returned if
@var{x} is negative zero.
@item FP_SUBNORMAL
@standards{C99, math.h}
Numbers whose absolute value is too small to be represented in the
normal format are represented in an alternate, @dfn{denormalized} format
(@pxref{Floating Point Concepts}). This format is less precise but can
represent values closer to zero. @code{fpclassify} returns this value
for values of @var{x} in this alternate format.
@item FP_NORMAL
@standards{C99, math.h}
This value is returned for all other values of @var{x}. It indicates
that there is nothing special about the number.
