Real array in UNIX script

[Disruptive]

Hi

I am keen to create an array which stores real numbers which I can then loop through. I have tried using the bash script, but I cant see any literature which states whether I can actually get real numbers into the arrays. The sort of code I have put together is:

#!/bin/bash


KT[1]= 1.0

or I have tried...

KT[2]= "1.2"

Can I do this??

How can I get real numbers into the arrays.

What do you want to do in a shell script with real numbers ?
I think that awk is best suited for that.

Hope This Helps, PH.

I am using the script to run through a series of combinations which will be inserted into files and then run using awk for example. However I have a complicated range of numbers and have listed them in an array which I can loop through. I can think of a better or smarter way to do it, I just cant seem to get those numbers into the array elements.

Is there a way of getting the numbers in?

ksh93 handles real numbers wih typeset -E (or -F).
I don't know if bash does.

There is no reason why you can't store real numbers in an array in ksh or bash provided you aren't planning to perform any calculations with them. The shell will just treat them as strings.

[tt]$ KT[1]=1.0
$ KT[2]=1.2
$ KT[3]=1.5
$ i=1
$ while ((i<=${#KT[*]})) ; do echo ${KT[$i]} ; ((i=i+1)) ; done
1.0
1.2
1.5
$[/tt]
