Why Does My Division Result in Zero Despite Non-Zero Inputs?

Unexpected Zero Division Results: A Common Pitfall

Dividing numbers can sometimes yield surprising results, like getting zero even when both inputs are non-zero. This often stems from how programming languages handle data types during calculations.

Consider this code example:

<code>decimal share = (18 / 58) * 100;</code>

Here, 18 and 58 are treated as integers. Integer division always produces an integer result; any fractional part is truncated. Therefore, 18 divided by 58 results in 0.

The solution is to ensure that the division is performed using decimal data types:

<code>decimal share = (18m / 58m) * 100m;</code>

The "m" suffix explicitly casts the numbers as decimals. This forces a decimal division, providing the accurate, non-zero result. This simple change prevents the truncation error and solves the problem.
