How to remove decimal value from sugar formula

subStr($name,0,subtract(strlen($name),7))
where $name is your field with value   Project -2.000000

You are treating a number like a string here and assuming that the number will always have 6 decimal places, which could change if anyone changes the precision on the definition of the field, I would respectfully recommend against doing that.

That is an example of how to cut unnecessary text from the string
Also, users do not change precisions for the fields, thought

However, I totally agree that fixing the cause, which seems in the precision set, is the best solution
