LibreOffice version history
We executed the same test cases under each LibreOffice release to show exactly when CEILING.MATH’s support changed — not documentation claims, real results.

| =CEILING.MATH(24.3,5) | Rounds 24.3 up to the nearest multiple of 5. Source: https://support.microsoft.com/en-us/office/ceiling-math-function-80f95d2f-b499-4eee-9f16-f795a8e306c8 (worked example table) | 25 | 25 | Matched |
| =CEILING.MATH(6.7) | Significance and mode both omitted -> defaults to nearest integer (significance 1). Source: Microsoft CEILING.MATH docs. | 7 | 7 | Matched |
| =CEILING.MATH(-8.1,2) | Negative number, mode omitted -> unlike the modeless legacy CEILING function, CEILING.MATH's default for negative numbers rounds TOWARD zero. | -8 | -8 Microsoft worked example: CEILING.MATH(-8.1,2) = -8 ('rounds -8.1 up (toward 0) to the nearest multiple of 2'). This is the modern, explicit-mode successor to legacy CEILING and was designed to match LibreOffice/ODF's CEILING(...,...,Mode) semantics for the default case. |

| =CEILING.MATH(-5.5,2,-1) | Negative number with a nonzero mode argument -> rounds away from zero instead of the toward-zero default. | -6 | -6 Microsoft worked example: CEILING.MATH(-5.5,2,-1) = -6 ('rounds -5.5 down (away from 0) ... with a mode of -1'). Mode only affects negative numbers; any nonzero mode reverses the default direction. |
