+.Sh LIBRARY

+.Sh SYNOPSIS
+.In math.h
+.Ft double
+.Fn nan "const char *s"
+.Ft float
+.Fn nanf "const char *s"
+.Sh DESCRIPTION
+The
+.Dv NAN
+macro expands to a quiet \*(Na (Not A Number).
+Similarly, each of the
+.Fn nan ,
+and
+.Fn nanf
+functions generate a quiet \*(Na value without raising an invalid exception.
+The argument
+.Fa s
+should point to either an empty string or a hexadecimal representation
+of a non-negative integer (e.g., "0x1234".)
+In the latter case, the integer is encoded in some free bits in the
+representation of the \*(Na, which sometimes store
+machine-specific information about why a particular \*(Na was generated.
+There are 22 such bits available for
+.Vt float
+variables, 51 bits for
+.Vt double
+variables, and at least 51 bits for a
+.Vt long double .
+If
+.Fa s
+is improperly formatted or represents an integer that is too large,
+then the particular encoding of the quiet \*(Na that is returned
+is indeterminate.
+.Sh COMPATIBILITY
+Calling these functions with a non-empty string isn't portable.
+Another operating system may translate the string into a different
+\*(Na encoding, and furthermore, the meaning of a given \*(Na encoding
+varies across machine architectures.
+If you understood the innards of a particular platform well enough to
+know what string to use, then you would have no need for these functions
+anyway, so don't use them.
+Use the
+.Dv NAN
+macro instead.
