ksh on linux - declaring decimals

[KateDart]

Hey guys, I'm new to linux and I'm trying to bring some korn shell code over from an HP-OS operating system. In HP, decimal numbers do not have to be declared, but in linux I"m getting errors for the decimal points. Can someone tell me how to declare my variables? Something like:
integer abc=0
only for decimal numbers.

Hi.

Welcome to the forum.

#!/bin/ksh

# @(#) s1       Demonstrate floating-point.

# man ksh: float='typeset -lE'

echo
echo "(Version information from local command \"version\")"
version >/dev/null 2>&1 && version =o $(_eat $0 $1)

float a=1.1
typeset -lE b=3.3

echo
printf " Difference between $b and $a is %f\n", $(( b-a ))

exit $?

Producing:

$ ./s1

(Version information from local command "version")
Linux 2.6.22-3-686
ksh 93s+

 Difference between 3.3 and 1.1 is 2.200000

Best wishes ... cheers, drl

Are you using the real korn shell, or pdksh (a poor imitation, IMO)?
