Is it possible to send something like 200*100,000 as an input to calc?

Documentation says Long numbers can be hard to read if they have too many digits. Press d g (calc-group-digits) to enable Grouping mode, in which digits are displayed in clumps of 3 or 4 (depending on the current radix) separated by commas.

When using (calc-group-digits) the digits are grouped in clumps of 3, for example the value of 200*100000 is shown as 20,000,000. It would be great if it would be possible to also give the input in clumps of 3 separated by comma in the minibuffer. I tried 200*100,000 but it didn't work.

    Not sure if what you want is doable with the current code, but 200*100*1000 is only one character longer than what you want. – npostavs Feb 05 '18 at 01:08
  • @npostavs Yes that number was easy, but for a number like 123438478 is mot easy. – Name Feb 05 '18 at 10:19
  • @npostavs for 2001001000 you need to switch to the algebraic mode, that means even more typing... – Dieter.Wilhelm Feb 23 '18 at 10:28
  • If , isn't used by calc at all, it would be possible to advise the function which reads input to strip out commas before it gets the string. –  Oct 21 '18 at 15:37

I'm using the scientific notation 200e5 to input large numbers in calc (or even more clearly the engineering notation 20e6 for your case).
