Re: number and its decimal

Heedunk, I'm not sure I follow.. in math, there is no "number of decimal places", unless you're talking about two numbers after the decimal, or three numbers before the decimal. I assume you want to display what the largest column is..? As in ten, hundred, or a thousand?

Maybe someone has a better solution, but I think you'll need a case statement... in ksh:
Code:
a=432.27
b=${a%%.*}
case ${#b} in
  2) echo "tens" ;;
  3) echo "hundreds" ;;
esac

Returns:
> hundreds
