Getting the remainder of an integer division by one always results in zero, making the operation redundant. Using minus one as the divisor can
cause panic or overflow issues.
Code examples
Noncompliant code example
let x = 1;
let a = x % 1; // Noncompliant: Remainder of division by one.
let b = x % -1; // Noncompliant: Remainder of division by minus one.
Compliant solution
let x = 1;
let a = 0; // Compliant: Directly assigning zero instead of using `% 1`.
let b = 0; // Compliant: Directly assigning zero instead of using `% -1`.
