# V6113. Suspicious division. Absolute value of the left operand is less than the value of the right operand.

The analyzer has detected the modulo or division operation with integers where the absolute value of the left operand is always less than the absolute value of the right operand. Such an expression contains an error or is redundant.

Here is an example:

    int a = 5;
    int b = 10;
    int result = a / b;  // Result: 0

As a result of executing this code fragment, the 'result' variable is always zero. Such operations can be logic errors: a programmer used an incorrect value or specified the wrong variable.

If the operands are specified correctly and the exact value of the division result is required, you can fix the code fragment by doing an explicit type casting before the division:

    int a = 5;
    int b = 10;
    double result = (double)a / b;  // Result: 0.5

Such a case is not an error if the division operation is performed on real numbers:

    double a = 5;
    double b = 10;
    double result = a / b;  // Result: 0.5

When using the modulo operation, if the absolute value of the left operand is less than the right operand, the expression result is always equal to the left operand. Such operation is redundant. Here is an example:

    int a = 5;
    int b = 10;
    int result = a % b;  // Result: 5

This diagnostic is classified as:

CWE-682
