Extract N number of digits after the dot

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
