Description
When comparing floating-point values in unit tests using toBe, false negatives occur due to slight differences in precision. This issue leads to discrepancies like
Expected: 24.9
Received: 24.900000000000002Solution: Implement toBeCloseTo for Floating-Point Comparison
To mitigate this problem, Jest documentation recommends using toBeCloseTo instead of toBe for comparing floating-point values. This method allows specifying a precision level for comparison. Refer to Jest documentation for details.
