There was a problem hiding this comment.
I initially didn't consider how this would work with >1 integer digit. Switching to a IncrementNumberRounder ensures that it always formats it with 6 fractional digits no matter how many integer digits it has.

The team will only be taking critical changes into WinUI 2.8 as our current focus is to assist our users in moving from WinUI 2 to WinUI 3. This change did not meet the bar for a WinUI 2.8 servicing release, but is approved to merge into the WinUI 2 main branch for a WinUI 2.9. That being said, at this time, we have no plans for a WinUI 2.9 as we focus on advancing WinUI 3. We will also port this change to WinUI 3 and it will be present for applications that have migrated to WinUI 3 in an upcoming WinAppSDK release. Thank you for your contribution! cc: @bpulliam |

Description
printf() defaults to 6 digits. 6 digits are sufficient for most
users under most circumstances, while simultaneously avoiding most
rounding errors for instance during double/float conversion.
Closes #3959
Motivation and Context
FLT_DECIMAL_DIGis 9. With 12 significantly exceeding this,WinUI is incapable of presenting 32-bit floats. C defaults
to 6 digits for string conversions for this exact reason.
How Has This Been Tested?
Windows Terminal overrides its NumberBoxes the same way this PR does it.
