rounding numbers up or down

[jsweatherbie]

im not sure how to round a decimal number to a whole...... 
i have this macro to make feed and speeds and to apply it but the problem im having is that itll have a decimal and when i post it... it will error due to a decimal number with the rpm.

in the end im trying to make both feed and speed a whole number after it goes thru the formula.

//CREATED BY: JAMES 

REAL $drillRpm = 250/$tool.Diameter
EDIT RPM $drillRpm
RESET TOOLPATH FEEDRATE

REAL $drillIpm = '$drillRpm * 0.005'
EDIT FRATE '$drillIpm'

RESET TOOLPATH FEEDRATE

Try this:

//CREATED BY: JAMES 

INT $drillRpm = 250/$tool.Diameter
EDIT RPM $drillRpm
RESET TOOLPATH FEEDRATE

REAL $drillIpm = $drillRpm * 0.005
EDIT FRATE $drillIpm

RESET TOOLPATH FEEDRATE

Worked good

you can use the round() function:

//CREATED BY: JAMES 

REAL $drillRpm = 250/$tool.Diameter
$drillRpm = round($drillRpm,0)
EDIT RPM ${drillRpm}
RESET TOOLPATH FEEDRATE

REAL $drillIpm = $drillRpm * 0.005
$drillIpm = round($drillIpm,0)
EDIT FRATE ${drillIpm}

RESET TOOLPATH FEEDRATE

I think its better to change format of "Feed" in the post processor to "Integer". 

then you always get round numbers.
