Insert comma/point in a number

I have a temperature data in a char format without comma or point to divide the decimal and I want to insert a point after the second number (staring from the left):

char= 225800 and I want t=22.58

Can someone help me, please?

Thank you

I am not certain what you are doing.

I assume ‘char’ is a character vector. If so, this will work:

char = '225800';
t = str2double(char)*1E-4               % Double-Precision Numeric
tstr = sprintf('%.2f', t)               % Character Array

t =
   22.5800

tstr =
    '22.58'
