We've got a value with 4 decimal numbers like 39,8001. This should be shortened (not rounded) like these examples:
39,8000 should become 39,80
46.5760 should become 46.57
Format-number and round functions round decimal numbers to
This is not what should happen here.
A function like 'Floor' cuts everything behind the decimal character. Using this function it seems java uses a floating point.
Trying (Floor(input*100))/100, results in
39,79 (real input value *100= 3979,9999999999995)
Using this as input value works: (Floor((input*100)+0,0000000000005)/100
