Title: Rounding number in brains formula
Post by: rrc1962 on December 20, 2010, 05:57:14 PM

Can you round a number in a formula.  I need to round the output of a formula to zer decimal places.  IE 4.8973 needs to equal 5.  The VB script function Round() doesn't work.

Thanks

you would need to do a work around.
send the dec val to a UDRO, then in macropump, read in that udro, do a vb round on it, repost it to another udro
in brains read in that rounded udro val and do what ever.

Just in case someone else in the future is looking for another solution to this.

I managed to round a value in brains using a formula someone had posted at stackoverflow.

The attached image is of an example rounding the spindle frequency in Hz.

I entered s500 in MDI in mach3, the formula I have then takes the spindle speed and divides by my motors RPM at 60Hz (1765), I then multiply by 60 to get the Hz number.
