Negative to positive

[Acro Engineering]

What is the simple way to change a number from negative to positive in the post? Also, is there a round up funtion?

[MultiAxGod]

Not quite sure why you would want to do this, but an easy way is to multiply by -1 which will switch your sign (x*-1). Easier to move the part to right quadrant.

FYI:If your mirroring a part, this will change your cut from climb to conventional.

The system handles rounding by the number of places after the decimal that you signify for output, if your question is about posted output values.

We need some more information on exactly what you are trying to accomplish. Normal rounding in the post is controlled by the Format Statements which tell Mastercam how many decimal places to output.

 

Are you trying to round up to the next whole number regardless of the decimal value? Like you want 16.1 to round up to 17?

[Acro Engineering]

That's exactly what I'm trying...

 

I'm not posting path information with the change from negative to positive but doing some calculations for adaptive feed rate...

Sorry, some how re-posted

round function on MP ->

 

rounded = round(value)

[Acro Engineering]

Here is what worked:

if a > round(a), a = round(a) + 1

else a = round(a)

May I ask what "a" mean there?

===================

[Colin Gilchrist]

"a" is a variable that Acro has initialized. It is a "container" to hold a number.

 

Here is how would that line of code would look if it was written as a sentence:

 

If the value of the variable "a" is greater than the value of the rounded variable "a", Then the new value for the variable "a" will be equal to the rounded value of "a" plus the number 1.

maybe

 

a = round (a+.5)

Colin. Thank you very much.
