Question

I want a function that is passed an integer, and if that integer is over a certain value (1000 in my current case) I want to perform some division on it so I can ultimately return an abbreviation of the original integer.

For example:

1000 = 1
1001 = 1
1099 = 1
1100 = 1.1
1199 = 1.1
1200 = 1.2
10000 = 10
10099 = 10
10100 = 10.1

It’s the division and rounding side of things that has been causing me problems.

What would be the most suitable method to give me the results above?

Answer 1

How about:

int dividedBy100 = x / 100; // Deliberately an integer division
decimal dividedBy1000 = dividedBy100 / 10m; // Decimal division
string result = dividedBy1000.ToString();

I would advise using decimal here rather than float or double, as you fundamentally want decimal division by 10.
