Check an exact decimal total

Compare an exact decimal total

Enter decimal values using a decimal point and place each value on its own line. The checker performs decimal arithmetic from the text representation, so a simple sum such as 0.10 + 0.20 can be compared with 0.30 without a binary floating-point display artifact.

The result reports the calculated total, the expected total and their difference. It checks the numbers that you supplied; it cannot verify a source document, a missing row, a currency conversion or a rounding policy.

Normalize ambiguous notation first

A formatted amount such as 1.234,50 needs an explicitly chosen decimal and grouping convention. Use the table normalizer for that transformation rather than removing punctuation by guesswork.

Example calculation

Check an exact decimal total: worked out from the values already filled in the form above.

  0.10
  0.20

• Expected total: 0.30

Result
