hi,

b = round(a 10^n) / 10^n

Where 'n' is the desired number of decimal places.

Hello. Thank you for the help.

Is the round command an official command, in so why is it not in the list of all the commands?

What do a and b mean, are they referring to objects? Can I change the letters to other letters, will the command still work?

Am I correct to assume, that I have to plug this command into the input bar? Am I correct to assume that round is a command?

Hi,

Is the round command an official command

is not a command, is a official predefined function link

You can see the predefined functions also in 'Input Help' / 'Mathematical Functions'

What do a and b mean, are they referring to objects? Can I change the letters to other letters, will the command still work?

yes they referring objects, b must have the type 'number'

<nameNewNumber> = round(<nameNumber> 10^<numberDecimalPlaces>) / 10^<numberDecimalPlaces>

Am I correct to assume, that I have to plug this command into the input bar?

yes
