UnverifiedIEEE 754 double-precision floating point (float64) can only exactly represent fractions whose denominator is a power of 2, and decimal fractions like 0.1 and 0.2 are infinite repeating fractions in binary, so they are necessarily truncated when stored.73% similarUnverifiedIEEE 754 floating-point numbers do not satisfy the associative and distributive laws of the real numbers, and rounding errors accumulate and propagate.71% similarUnverifiedDue to IEEE 754 floating-point precision limitations, directly using EXPECT_EQ for floating-point comparisons will almost certainly lead to false failures, and EXPECT_NEAR should be used to specify a tolerance.64% similarUnverifiedThe batch secondary account sharing model has problems such as time-limited quota resets, frequent disconnections, and degraded model quality.61% similarUnverifiedThe four-number reconciliation refers to four figures: frozen inputs, accepted submissions, returned results, and committed updates; under normal conditions frozen inputs ≥ accepted submissions ≥ returned results, and committed plus quarantined should exactly cover all result rows.61% similar
