Insert a limit in a measure to avoid below 0 or above 100

[Anonymous]

I have a 3 measures related to absence:

1 Calculate number of working days in month - (2.5 days leave allowed)

Measure 5.1 =

VAR _Month = CALCULATE(COUNT(DimDate[Days in Month]),FILTER(DimDate,'DimDate'[WorkingDays] <>BLANK()))

VAR _lastday=

COUNTROWS(

FILTER(DimDate,'DimDate'[WorkingDays] <>BLANK()))-2.5

RETURN

IF ( ISBLANK ( [AbsentByDay] ), BLANK (), _lastday )

2. Number of absence days from dates : [AbsentbyDay]

3. Measure 1 and Measure 2 subtracted

Measure 5.5 =

VAR _Month = CALCULATE(COUNT(DimDate[Days in Month]),FILTER(DimDate,'DimDate'[WorkingDays] <>BLANK()))

VAR _lastday=

COUNTROWS(

FILTER(DimDate,'DimDate'[WorkingDays] <>BLANK()))-2.5

RETURN

IF ( ISBLANK ( [AbsentByDay] ), BLANK (), _lastday )-[AbsentByDay]

My question is : is there a way to limit the NET values in table 3 from going below 0 / over 100 

Thanks in advance, apologies if I haven't explained this properly.

How about wrapping the result inside a MAX

MAX(answer that may be negative,0)

if it is negative, you get zero instead
