Earthquake Magnitude Comparison (energy ratio) implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Computation or source lookup only

Input and validation requirements

At magnitude difference ΔM = 1000, both mathematical ratios exceed JavaScript's finite numeric range and evaluate to Infinity in plain JavaScript arithmetic. The instrument should detect and flag this overflow.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

  "working": "ΔM = 6.0 − 5.0 = 1.0. Energy ratio = 10^(1.5 × 1.0) = 10^1.5 = 31.6227766017. Amplitude ratio = 10^1.0 = 10.0."
