Class: VarianceBasedPrecisionCalculator
Serialization.PrecisionDetection.VarianceBasedPrecisionCalculator(qualityFactoropt)
A precision calculator based on the error introduced after rounding
Constructor
new VarianceBasedPrecisionCalculator(qualityFactoropt)
Parameters:
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
qualityFactor | float | <optional> | 0.5 | Quality factor is used during optimal precision detection.Valid values range between 0 and 1. A value of 0 is considered 'worst quality / smallest size', a value of 1 - 'best quality / max size'. |
