Excel functions extend your range of options when calculating an item or a condition.
Below are the Excel functions, with examples, that you can use when creating a custom Item Formula in STACK.
Find by Excel function name
A
Absolute Value (ABS)
Returns the absolute value of a number, a number without its sign.
abs(Number)
EX: abs([MeasuredLinear]*-4.23)
= abs([144.89]*-4.23)
= abs(-612.88)

= abs([144.89]*-4.23)
= abs(-612.88)
= 612.88
And

EX: if(and([MeasuredLinear]<0,[MeasuredLinear]<=8,[MeasuredLinear]/8,0)
= if(and([4]>0,[4]<=8),[4]/8,0)
