Back port ksh93v- float, int, and exp10 changes from math.tab (#299)

Browse source 
src/cmd/ksh93/data/math.tab:
- Added exp10().
- Remove int() as being an alias to floor().
- Created entries for local float() and local int() which are
  defined in features/math.sh.

src/cmd/ksh93/features/math.sh:
- Backport floor() and int() related code from ksh93v-.

src/cmd/ksh93/sh.1:
- Sync man page to math.tab's potential functions.
