How i can get the last digit from a integer?

Some examples:

3451
789
20
1

(retard example, ftw)

Thanks in advance.

I assume it'd be something like this.

PHP Code:

new i = 26

new number[] = num_to_str( i )

new lastdigit = str_to_num( number[ sizeof number - 1 ] )
// or if you want it as a string
new lastdigit = number[ sizeof number - 1 ]

Suck Method.

PHP Code:

stock get_last_num( const int )
{
    return int - 10 * (int / 10);
} 


I think that is correct. Just Test. I don't!!!



EDIT: Exolent method rocks!!

What? That makes no sense.

26 - 10 * (26 / 10 )
non-PEMDAS: 41.6
PEMDAS: 0

You guys are either retarded or didn't think.

new iNumber = 123456;

new iLastDigit = iNumber % 10;

// iLastDigit = 6

EPIC PWNAGE

Programming require math skills... Actually, programming is just math hiding behind identifiers and operators.

What exactly does the modulo operator return? I'm aware that it has something to do with the remainder, but that operation makes no sense at all to me. I would've thought it'd return 0, since the remainder of 123456 / 10 is 0.

You fail at math if you think that. % returns the remainder of the division problem. 6 / 10 leaves you with a remainder of 6...

Oh, come to think of it, that was quite a dumb statement.

My bad.

% work like this:

I want to do: 20 % 8;

PHP Code:

Well:
0    1    2    3    4    5    6    7: ( 0 to X % (this-1) )

0    1    2    3    4    5    6    7
8    9   10   11   12   13   14   15
16  17   18   19   20 


So 20 % 8: 4

Algo you can think:

20 / 8 = 2
20 % 8 = 4.

4 / 8 = 0.5

So: 8 * 2 + 4 = 20;

Just a math lesson.
