I have an integer than has a number like, 5349, and I want to get the value of each place, thousands, hundreds, tens, and ones. I can get the thousands place by diviing 5349 by 1000 and getting 5.349, and then i get 5. But i can''t figure out how to get the 3, 4 or 9 for the other places. Its probably something easy, but i can''t seem to figure it out right now. Thanks for any help. t2sherm ô¿ô

5349

thousands = 5349 / 1000 = 5
hunderds = 5349 / 100 - thousands * 10 = 53 - 50 = 3
decimals = 5349 / 10 - thousands * 100 - hundreds * 10 - 534 - 500 - 30 = 4

units = 5349 - thousands * 1000 - hunderds * 100 - tens * 10 = 5349 - 5000 - 300 - 40 = 9




get it?

To get the last digit of any number, just mod that number by 10

onesPlace = number % 10

It''s fairly easy to get the other places as well, just divide by a multiple of 10 after modding by the needed value (hundreds, thousands, etc... for instance:

tensPlace = (number % 100) / 10

hundredsPlace = (number % 1000) / 100

Also, in your example, it only works like you want it to if you assume that the number is 4 digits long... don''t assume that after truncating, you''ll get a single digit value: (e.g.)

15349 / 1000 = 15.349 = (truncated) 15 (not the thousand''s place!)

349 / 1000 = .349 = (truncated) 0 (not what you want!)


Can I ask what you''re using this code for, out of curiosity?

Monday is an awful way to spend one seventh of your life.

To get the 100th place: 5349/100 = 53 and then 53%10 = 3

To get the 10th place: 5349/10 = 534 and then 534%10 = 4

To get the One place: 5349%10 = 9

Incase you are wonder, the % sign stands for modulo, it returns the remainder of the division, so 7%5 would return 2.

Another thing is , if you are using pascal, u have to typ 7 mod 2

hope this helps

Wow, thanks for all the replies!

I am making a game (in C++ w/ DirectX 7), and I want to write out the score, and right now i am just converting the integer to an array of chars, and then writing it out w/ the GDI, and besides being terribly slow, the score doesn''t look good, so I''m going to make the digits 0 - 9 in photoshop, and then extract the different place values, and blit the correct combination of numbers so it prints the score.

Ummm... there are two easier solutions to your problem.

There''s a function called itoa() that will convert an integer to an array of characters.

Also, there''s a function called sprintf() that will bring any combination of basic types in and build a string out of them.

Just a suggestion, I know it''s possible that you already know about these and just wanted to write your own, but if you didn''t know, then now you do
