Rounding values

Luc_ROLLAND

Hello !
I try rounding calculations,

PosMin=2.9cm
PosMax=5.5cm 

#PosMin+(((#PosMax-#PosMin)/5)*2)

return 3.94cm

but I need mathematical rounding, so I write :roundToPrecision(#PosMin+(((#PosMax-#PosMin)/5)*2),1)
or

roundToPrecision((#PosMin+(((#PosMax-#PosMin)/5)*2)),1)

or

roundToPrecision((#PosMin+(((#PosMax-#PosMin)/5)*2)),1))cm
(

I hope 3.9cm

but I obtain an error !
(as with some others variants).

I don't understand where I'm wrong, but I'm newbee with OnShape ...
Please help me.

Or if PostMin and PostMax have to have units, this would work.

roundToPrecision(#PosMin/(cm)+(#PosMax-#PosMin)/(5 cm)*2,1)cm

roundToPrecision only works with numbers, not ValueWithUnits, so you should use:

PosMin=2.9
PosMax=5.5
roundToPrecision(#PosMin+((#PosMax-#PosMin)/5)*2,1) * cm

Or if PostMin and PostMax have to have units, this would work.

roundToPrecision(#PosMin/(cm)+(#PosMax-#PosMin)/(5 cm)*2,1)cm

A little bit complex.
Many thanks.
