Addressing Precision Issues in Floating-Point Value Comparison

Open ManuelLoaizaV opened this issue 1 year ago • 0 comments

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: 24.900000000000002

Solution: 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.
