WebJan 3, 2024 · @T.Sar The technique you describe and the semantics described in the answer are different. Semantics is whether the programmer intends the answer to be a floating-point or fractional value; the technique you describe is the division by reciprocal multiplication, which is sometimes a perfect approximation (substitution) for an integer … WebDividing an integer by an integer gives an integer result. 1/2 yields 0; assigning this result to a floating-point variable gives 0.0. To get a floating-point result, at least one of the operands must be a floating-point type. b = a / 350.0f; should give you the result you want.
