Add this one to your toolkit too:-)

People here have been doing arithmetic using $(()) which is fine, but
only does integers. Sometimes one wants a decimal|floating point, so
this can often be used:

06:55 [EMAIL PROTECTED] ~]$ echo 'scale=4;(14595.470+200.00)/4331.00' | bc
3.4161
06:55 [EMAIL PROTECTED] ~]$

I often do that for simple financial calculations (that's one of them).

For more,
  man bc
