bc arbitrary precision cal lang
Hello all,

I don't know ksh that well but when I try to run a simple script using the bc command I get "unexpected '.' ", has any one encouter this or help me. I'm running under redaht 7.2. Here is a simple example:
Code:
#!/bin/ksh
#
kilo=`echo "2495 * .25"|bc`
if [ $kilo -lt 3000 ]
then
   echo "LESS THEN"
else
   echo "GREATER THEN"
fi

I get 1[9]: 623.75: unexpected '.'
GREATER THEN

THANKS

larry,
When I ran it in Solaris 8, I got:

LESS THEN

Pretty strange. Anyone have any ideas?

Most versions of ksh only support integer arithmetic. If you try to operate on a number like 623.75 the results will be unpredictable.
