 For eg. If one of my number is 1.23456789 then I want '234' out of it. I want only the 3 digits after the decimal point. Can you help me?

Best Answer

To get the digits in a scalar numeric:
>> x = 1.23456789;
>> N = 4;
>> n = fix(rem(x,1)*10^N)
n = 2345
then to convert this to a string:
>> s = sprintf('%.0f',n)
s = '2345'
and finally to get the digits in a numeric vector:
>> v = s-'0'
v = [2,3,4,5]
