 The value of @var{x} is either plus or minus infinity (@pxref{Infinity

 The value of @var{x} is zero.  In floating-point formats like @w{IEEE

 @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.
