Some mathematical operations are unnecessary and should not be performed because their results are predictable.

For instance, `anyValue % 1`

will always return 0, as any integer value can be divided by 1 without remainder.

Similarly, casting a non-floating-point to a floating-point value and then passing it to `Math.round`

, `Math.ceil`

, or
`Math.floor`

is also unnecessary, as the result will always be the original value.

The following operations are unnecessary when given any constant value: `Math.abs`

, `Math.ceil`

, `Math.floor`

,
`Math.rint`

, `Math.round`

. Instead, use the result of the operation directly.

The following operations are unnecessary with certain constants and can be replaced by the result of the operation directly:
