Why does integer division sometimes give unexpected results?

Integer Division Errors: Addressing the Discrepancy

Dividing integers yields counterintuitive results due to the operation being performed as integer division, where the fractional part of the result is discarded. This disparity manifests in incorrect division outcomes.

To resolve this issue, consider the following:

  1. Float Conversion:

    • Utilize the float type to force the numerator to be treated as a float, consequently promoting the denominator to a float as well. This enables float division rather than integer division.
    • For instance, replace float res = quantity / standard; with float res = (float) quantity / standard;.
  2. Float Denominator Literal:

    • If dealing with literal values, append the 'f' suffix to the denominator to explicitly specify it as a float.
    • For example, alter float f = 6800 / 500; to float f = 6800f / 500; to ensure the denominator is a float.
