standard
Floating-point standard that mandates correct rounding for basic arithmetic and square root but leaves transcendentals such as pow unspecified.
No evidence-backed relationships are recorded.
The engine reads the leading bytes of a 256-bit hash as two integers a double holds exactly and adds them in one operation, matching the server's single Long-to-Double rounding. Crash avoids doubles entirely.
Reality
A UK migration guide puts a mid-size mainframe move at one to two years. The stated failure modes are packed-decimal typing and business logic nobody documented, not the target language.
Reality
A team that sells precision guardrails found its own browser pages calling JSON.parse directly, rounding a snowflake ID by 1,788 with no error. The server path was safe. The client path was not.
Reality
A dev.to post argues the expensive defect is not float drift but a money type that carries an amount and nothing else. Swapping doubles for Decimal leaves the hole open.
Reality
TinyColor's suite asserts contrast ratios to sixteen decimal places. Running it unmodified against a WebAssembly build of a Rust port showed that Math.pow disagrees with itself across platforms.
