Similar to Dave's

Code: Select all

@For /F %%A In ('PowerShell -C "[math]::round(7/3,2,1)"') Do @Echo(%%A&Timeout 5

The 1 after the comma I use to make sure that the result is 'away from zero' midpoint rounded.

Hmm, this does not seem to work:

for /f %%A in ('powershell -command "& {[math]::round(9/8,2)}"') do set "bbb=%%A"

outputs 1,12 (=wrong) instead of 1,13 (=correct)

If you look closely it is not the same code as you quoted from Compo.

Ok, little mistake from me

Thank you
