How to round to whole number within macro?

[Kolbi]

Is there a way to round a value to a whole number, from within a macro? For example:

sensors.analog[2].lastReading = 123.4 - how to get reading as 123?
sensors.analog[2].lastReading = 123.6 - how to get reading as 124?

Thanks much,
Kolbi

See the floor function, https://duet3d.dozuki.com/Wiki/GCode_Meta_Commands#Section_Functions.

@dc42 Thanks!
I'll play around with it when I get out of work.
Could you possibly give me a simple syntax / usage example?

Look up "floor function". It rounds down (towards minus infinity) to integer. So if you want to round to nearest integer, use:

floor(sensors.analog[2].lastReading + 0.5)
