Bug Description

In version 0.95.1, when running a Tukey post-hoc test, some results in the output table display incorrectly as “,00” instead of “1,00”.

• This happens when the expected value should be “1.00”.

• The leading digit before the comma/decimal point is missing.

• In earlier versions of JASP (for example, 0.19.3), this formatting issue did not occur — the leading digit was displayed correctly.

Results in JASP 0.19.3 (previous version)

Values were displayed correctly with the leading digit:

Results in JASP 0.95.1 (current version)

Some results incorrectly omit the leading digit:

Here is the JASP file I am using:

Expected Behaviour

Expected Behaviour

The results should display “1,00” instead of “,00” when the value is one.

More generally, it would be useful to have an option to always show the leading digit before the comma/decimal point, even if it is zero.

Example: show “0,05” instead of “,05”, or “1,00” instead of “,00”.

This feature would improve clarity, avoid misinterpretation, and keep consistency with earlier versions (e.g., 0.19.3).

Steps to Reproduce

Steps to reproduce:

1. Open JASP 0.95.1

2. Perform an ANOVA followed by a Tukey post-hoc comparison among groups

3. Check the result table for comparisons where the mean difference is 1.00

4. Observe that the table shows “,00” instead of “1,00”

Can you try 0.95.2?
Also 0.95.3 is coming out later today/tomorrow, it should be better too.

Could you provide me with the version you mentioned?

Im sorry, im confused with our weird numbering scheme.

0.95.2 comes out later today or tomorrow but you could test https://static.jasp-stats.org/Nightlies/WindowsZip/JASP-nightly-development-d4766a76c131ef29aca77a3e8b2980360d7fca1a.zip or https://static.jasp-stats.org/Nightlies/Windows/JASP-nightly-development-d4766a76c131ef29aca77a3e8b2980360d7fca1a.msi

Hello dear Joris, I just tested the version you provided me, and it still has the same error I had mentioned.
