Hello everyone How can I get the difference between a number and the next number divisible by 10 in c#?
Example.
15 should give 5. (20-15 =5)
21 should give 9. (30-21=9)
30 should give 0. (30-30=0)
Sorry for my english.
Thanks in advance.
Mod won’t work, that will give you the opposite of what you want. 21%10=1 not 9 like you want. What you should do is 10-(num%10). This will get you much closer. The only result that will be wrong in this case is 30, which will give a result of 10.
so:
This will give you the correct result everytime, although a bit cumbersome.
