We added the reference for three functions that have always existed but were never documented
Bound(expression, min , max) Limits a value to a maximum and a minimum
LBound(expression, min) Limits a value to a minimum
UBound(expression, max) Limits a value to a maximum
So for example Bound(Surprise%Q1, -100, 999) will limit the EPS surprise to values from -100 to 999.
Sorry about the missing doc.
