Hi guys,
suppose N=1234.4345
I would like to store in this variable the decimal number and the first two digits only after the dot.
(e.g. N=1234.43 )
Kind Regards.

You can use the most recent version of the round function, or use this emulation of it:
roundn = @(x,n) round(x .* 10.^n)./10.^n; % Round ‘x’ To ‘n’ Digits, Emulates Latest ‘round’ Function
N = 1234.4345
N = roundn(N,2)
N =
1234.4345
N =
1234.43
