Percent Yield Calculator 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.

Effect

Computation or source lookup only

Input and validation requirements

A theoretical yield of exactly zero causes division by zero and must be rejected. Negative yields also expose an unstated sign-validity convention.

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.

{
  "inputs": {
    "actual_yield": 8.5,
    "theoretical_yield": 10,
    "unit": "g"
  },
  "expected_outputs": {
    "percent_yield": 85
  },
  "working": "%yield=(actual/theoretical)×100=(8.5 g/10.0 g)×100=0.85×100=85.0%"
}
