Harrow Perf Notation Decoder
Decode a supplied harrow horizontalxvertical gauge notation without identifying perforator manufacture. Caller independently verifies observations, reference edition, units and applicability; not a grading-service certificate, authentication, conservation treatment, actual market price or legal/insurance entitlement.
Description
Compound perforation notation can express horizontal and vertical gauges as two positive numbers separated by x.
Compound perforation notation can express horizontal and vertical gauges as two positive numbers separated by x.1
This decoder parses that literal notation and preserves the numeric distinction without identifying a perforating machine.
When to use Harrow Perf Notation Decoder
Use this tool when you need to summarize the supplied collecting records or matched observations. Prepare independently verified observations, reference edition/context, and matching units or currency basis.
How to use Harrow Perf Notation Decoder and understand its results
- Prepare independently verified observations, reference edition/context, and matching units or currency basis.
- Enter notation, following the field table and calculation rules below, then run the tool.
- Read horizontalGauge, verticalGauge. For result objects, inspect the nested output fields below, including any missing evidence or selected indices.
- Correct any input issues and run again. Before using a successful result, review its units, signs, evidence coverage, and stated model or reference assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| notation | Notation | string | Required |
Require a string matching digits with optional decimal fraction, lowercase ASCII x, then the same number pattern. Reject spaces, signs, exponents, uppercase X, missing decimal digits, and nonpositive parsed values. Leading zeros are accepted but disappear in numeric outputs.
notation=positiveDecimal+"x"+positiveDecimal Read these symbols with the field meanings and branch or reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| horizontalGauge | Horizontal gauge | number |
| verticalGauge | Vertical gauge | number |
{
"input": {
"notation": "11x12.5"
},
"output": {
"horizontalGauge": 11,
"verticalGauge": 12.5
}
}Limitations and assumptions
Observations, reference edition, and applicability are independently supplied. Arithmetic and reference summaries do not provide authentication, a certified grade, or an actual market price.
Missing required fields, unknown fields, wrong types, and violated calculation rules return input issues.
Alternative or Complementary methods
For a related task, use Compound Perforation Notation Formatter (e.g. 11x12.5): Compound perforation notation records horizontal and vertical gauges together. This formatter joins supplied positive numeric gauges with lowercase x, without measuring teeth or selecting a catalogue rounding convention. For a complementary step, use Line vs Comb Perf Classifier from Pattern Notes: Line and comb perforation can leave different observed corner and row patterns. This classifier compares explicit evidence with caller reference requirements and may return more than one compatible method.
