Rounding in Equation 1

[Pachem]

Is it possible to round numbers using equations in SW?

Yes!

If you want to round, for example, to x.xx do the following

rouded result = (int(expression * 100+0.5))/100

The int function is available in equations.

But does the INT function round up or down to the nearest integer. If it's like excel it will round down to the nearest integer which is not a real rounding function. A true rounding function will allow the user to specify at what decimal place the rounding is to take place. I would have to say using the INT function is not a true rounding function.

The rounding down of the INT function is filtered by the +0.5 factor. The result is always correct.

The only problem about the above expession is that, on some criteria, x.5 should round to x-1 instead of x+1.

But the rounding of x.5 to x+1 it's a general accepted rule in engineering.
