Divide before Multiply
+A detector that identifies and corrects instances of division before multiplication to +ensure accurate mathematical operations.
+Why is it bad?
+Performing division before multiplication can lead to unexpected results due to precision loss and rounding errors:
+-
+
- Precision Loss: Dividing first can result in significant precision loss, especially when dealing with integers or fixed-point numbers. +
- Rounding Errors: Early division might cause rounding errors that propagate through subsequent calculations. +
- Unexpected Behavior: Misordered operations can lead to incorrect outcomes, making debugging and maintenance more challenging. +
Example
+let a: Int = 10;
let b: Int = 3;
let c: Int = 2;
// Bad: Division before multiplication
let result: Int = a / b * c;
Use instead:
+let a: Int = 10;
let b: Int = 3;
let c: Int = 2;
// Correct: Multiplication before division
let result: Int = a * c / b;
