Assigning bc output to a variable
I'm converting decimal to integer with bc, and I'd like to assign the integer output from bc to a variable 'val'.

E.g. In the code below: If b is 5000.000, lines 6 and 8 will output:
5000
(5000.000+0.5)/1 | bc

I'd like val to take the value 5000 though, rather than 5000.000

Does someone have any idea how to do that?
Code:
#! /bin/bash

while read b
do

    echo "($b+0.5)/1" | bc        # line 6 - works
    val= "($b+0.5)/1 | bc"        # line 7 - doesn't work
    echo $val                          # line 8

done < infile

anyremote2html

ANYREMOTE2HTML(1)					      General Commands Manual						 ANYREMOTE2HTML(1)

NAME

       anyremote2html - web interface for anyRemote acting as HTTP server

SYNOPSIS

       anyremote2html -w web-port -a anyRemote-port [-i directory-with-icons] [-s 16|32|64] [-r refresh rate] [--width integer] [-d]

DESCRIPTION

       The  overall  goal  of this project is to provide remote control service on Linux through Bluetooth, InfraRed, Wi-Fi or just TCP/IP connec-
       tion.

       anyRemote supports a wide range of modern cell phones like Nokia, SonyEricsson, Motorola and others.

       It was developed as a thin "communication" layer between Bluetooth (IR, Wi-Fi)-capabled phones and Linux, and in theory it could be config-
       ured to manage almost any software.

       anyRemote is a console application, but in addition there are GUI front-ends for Gnome and KDE and this web front-end.

       With the help of this interface any device which contains a web browser and which can connect to the PC with anyRemote by TCP/IP (GPRS, Wi-
       Fi, ...)  could be used as a remote control.

USAGE

       Run anyremote/kanyremote with "-s socket:<port>" option:
       anyremote -s socket:5000 -f <cfg. file>

       Run anyremote2html -a <anyremote port> -w <http port> -s 16|32|64 -i <directory with icons>
       For example:
       anyremote2html -a 5000 -w 5050 -s 64 -i /usr/share/pixmaps/anyRemote2html

       Run browser on device and connect to http://<ip.of.PC>:5050

       For easier use and configuration of anyRemote as well as anyRemote2html, use either kAnyRemote or gAnyRemote.
       Further information is shipped with the anyRemote package.
