Using Decimal points

[MED]

Help! I'm having problems adding numbers with decimal points. I need an answer with decimal points but it keeps rounding down.

This is the line that I'm using -
TOTAL=$((TOTAL+$AMT))

Can anyone point me in the right direction?
Thanks!

shell arithmetic is integer ONLY:
TOTAL=$(echo "${TOTAL}+${AMT}" | bc) vlad
+----------------------------+
| #include<disclaimer.h> |
+----------------------------+

which language do you use? shell, awk?..

MED:

Vlad's right about ksh arithmetic being integer only. That's ksh88. However, the ksh93 version does support decimal arithmetic:

This works on my solaris 7 box:

#!/usr/dt/bin/dtksh

let sum=$((5.2+6.3))
printf &quot;%f\n&quot; $sum
# end script

The dtksh shell is 93 compliant.
