Hi
I am trying to divide two numbers , I tried various method but not getting result

I tried
p1= `$(expr $diffcount / $basecount)`
p1= $(expr $diffcount / $basecount)
p1= expr(($diffcount / $basecount))
p1= $expr(($diffcount / $basecount))

diffcount and basecount values are generated by other expressions
I am getting values for those valuables . I am using Korn shell

thanks

You can try using bc instead of expr:

result=$( echo "scale=3 ; $diffcount / $basecount" | bc )
echo $result
0

Just add it here:

$diffcount * $othervariable / $basecount
0

Also note that in all of your examples there was a space after the "=" sign - there must be no spaces either side of the "=" when assigning values in shell.

Without the space, the second expression would have been what you wanted (as long as you don't mind an integer result).
