10%+10%

Why 10%+10%=10?

Answer 1

[Alan Stevens]

Because the % symbol indicates that the rest of the line is a comment. So the only non comment parameter Matlab sees is the first 10.

How should I enter? If 0.1 is not allowed

1/10

[Alan Stevens]

Seems crazy! However, how about

10/100

or define your own percent function, say

percent = @(x) x/100;

[Steven Lord]

What do you mean by "How should I enter?" Where/how are you trying to enter this data?

Using the input function? If so accept the data as text, process that text, and finally convert that text into a number.

in = input("Enter the percentage discount: ", 's');
if endsWith(in, "%")
    in = strip(in, "%");
end
inDouble = str2double(in)

Run this twice, the first time entering 10% at the prompt and the second time just entering 25.

In an inputdlg or an app? Get the data as text and proceed as I did with the input example above.

in = inputdlg("Enter the percentage discount")

In some other context like in a MATLAB script, function, or class file? If so please give more information.
