A simple way might be to use bc -l and use printf to print the required precision:
Code:
$ c=32
$ f=$(echo "$c / 5 * 9 + 32" | bc -l)
$ printf "%.1f\n" "$f"
89.6
$ printf "%.0f\n" "$f"
90

NAME
sieveshell - remotely manipulate sieve scripts SYNOPSIS
sieveshell [--user=user] [--authname=authname] [--realm=realm] [--exec=script] server[:port] sieveshell --help DESCRIPTION
sieveshell allows users to manipulate their scripts on a remote server. It works via MANAGESIEVE, a work in progress. The following commands are recognized: list list scripts on server. put <filename> upload script to server. get <name> [<filename>] get script. if no filename display to stdout delete <name> delete script. activate <name> activate script. deactivate deactivate all scripts. OPTIONS
-u user, --user=user The authorization name to request; by default, derived from the authentication credentials. -a authname, --authname=authname The user to use for authentication (defaults to current user). -r realm, --realm=realm The realm to attempt authentication in. -e script, --exec=script Instead of working interactively, run commands from script, and exit when done.
