- Move the functions presently described in in ieee(3) to their own

  manpages.  They are not very related, so separating them makes it
  easier to add meaningful cross-references and extend some of the
  descriptions.
- Move the part of math(3) that discusses IEEE 754 to the ieee(3)
  manpage.

+.Sh DESCRIPTION
+.Fn remainder
+and
+.Fn remainderf
+return the remainder
+.Fa r
+:=
+.Fa x
+\-
+.Fa n\(**y
+where
+.Fa n
+is the integer nearest the exact value of
+.Bk -words
+.Fa x Ns / Ns Fa y ;

+moreover if
+.Pf \\*(Ba Fa n
+\-
+.Sm off
+.Fa x No / Fa y No \\*(Ba
+.Sm on
+=
+1/2
+then
+.Fa n
+is even.
+Consequently
+the remainder is computed exactly and

+But
+.Fn remainder x 0
+and
+.Fn remainder \*(If 0
+are invalid operations that produce a \*(Na.
