Do decimal places matter when doing logical comparison/expression?

walkerist79 — Fri, 22 Apr 2022 05:14:50 GMT

CODE# 1

IF GROSS_PRICE <> '0,00' AND NET_PRICE <> '0,00' .
 "PRINT SOMETHING HERE"

CODE# 2

IF GROSS_PRICE <> '0' AND NET_PRICE <> '0' .
 "PRINT SOMETHING HERE"

Will these code have different results?

SAP inside format for decimal is the dot, not the coma. Did you try with a beautiful dot ?

You are comparing characters, not numbers, so "decimal places" don't mean anything.

If gross_price and net_price have numeric data types, ABAP will convert characters into numbers before comparing, and expects a valid number inside the quotes, i.e. comma is invalid (see ABAP documentation).

Of course, if they have numeric data types, you should write:

IF GROSS_PRICE <> 0 AND NET_PRICE <> 0.
 "PRINT SOMETHING HERE"

Nice interview question by the way. I expect the interviewer to hear how comfortable you are with talking about ABAP concepts, not to give the "right answer".

even with ' it works

DATA montant TYPE kbetr.

montant = 10 / 3.
IF montant GT '3.2'.
  WRITE 'Cassis'.
ENDIF.
IF montant LT '3.34'.
  WRITE 'Pomme'.
ELSE.
  WRITE 'Poire'.
ENDIF.
