I previously asked how to convert age represented as year.months: 12.06 in to decimal equivalent, in this case 12.5. Fo the second step of my problem, I would like to be able to convert this decimal back to the year.month format after I have been able to run a calculation.
The original answer that came back and worked perfectly for step 1 was:
=regexextract(trim(F4), "^\d+") + regexextract(trim(F4), "\d+$") / 12
but as I am unfamiliar with regextract() I was unable to reverse engineer the formula to go from decimal to year.month.
