Relation for rounding to nearest integer

[Korichnevijgigant]

I was recently grappling with this problem when putting together a family table. I was having trouble rounding a calculated value to the nearest integer to be displayed on a note in the drawing.

Before trying a lot of different calculations I did a google search and found this

Description: How to use round function
Applies To:
Pro/ENGINEER Wildfire 2.0 - 5.0 all datecodes,
Creo Elements/Pro 5.0 all datecodes
Creo Parametric 1.0 - 2.0 all datecodes

Resolution:
There is no direct function for round in relation than floor() and ceil().
To get mathematical round use one of the following formulas
no decimal place: A=floor(B+0.5) or A=ceil(B-0.4)
one decimal place: A=floor(B*10+0.5)/10 or A=ceil(B*10-0.4)/10
two decimal places: A=floor(B*100+0.5)/100 or A=ceil(B*100-0.4)/100

hope this helps somebody
