Extract two frist numbers form a column

2 次查看(过去 30 天)
Hi,
I have a column with 400 000 variables that look something like this:
68.092
67.011
76.949
etc.
I would like to extract the two first numbers into a new column such that I get a column that looks like this:
68
67
76
If it matters, the column is categorical.

A = [68.092
67.011
76.949] ;
integ = floor(A);
fract = A-integ;

Thank you for your reply! Unfortunately the floor function only returns me NaNs.

If it's categorical you need to convert it to doubles first.
A = categorical([68.092; 67.011; 76.949]); %Creating your categorical Array.
B = double(string(A)); %Converting and shortening it.
B = floor(B);
B =
68
67
76
Hope it works. Pozdrav.

Hi Emir,
Thank you for your reply. Converting to double only returnes me NaNs and therefore the floor function does not work either. I managed to do it in another program though but highly appreciate your time and response.
Hvala puno! Pozdrav.
