Escutcheon of Pretence Size Proportion Calculator
Observed escutcheon-of-pretence width fraction, not entitlement to bear it.
Description
An inescutcheon's width can be compared with the outer shield's width.
An inescutcheon's width can be compared with the outer shield's width.1
A proportion measures size rather than rights to display the smaller shield.
When to use Escutcheon of Pretence Size Proportion Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Establish the source tradition, viewing frame, coordinate units and independently annotated features.
How to use Escutcheon of Pretence Size Proportion Calculator and understand its results
- Establish the source tradition, viewing frame, coordinate units and independently annotated features.
- Enter inescutcheonWidth, outerShieldWidth, using the field meanings and rules below, then run the tool.
- Read result.observedFraction, using the output meanings and calculation rules below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| inescutcheonWidth | Inescutcheon width | number | Required |
| outerShieldWidth | Outer shield width | number | Required |
Use a positive outer-shield width and nonnegative inescutcheon width no greater than it. Divide the inner width by the outer width.
widthFraction=inescutcheonWidth/outerShieldWidth Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or reference | object |
| result.observedFraction | observed Fraction; dimensionless fraction, not a percent | number |

}Limitations and assumptions
The value describes one width ratio only. Height, placement, shape, entitlement and other proportions are not established.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
