The DigitationPolicy type defines a discriminated union used to specify the policy by which Normals are converted to Digits.
If a Normal value is 'between' two Digits then this policy lets you decide which Digit to use.
The cases are:
| Case Name | Map Normal To |
|---|---|
| UseNearest *1 | The nearest Digit *2 |
| TendDownwards | The lower of the two Digits *3 |
| TendUpwards | The higher of the two Digits *4 |
| TendOutwards | The Digit which is lower when the value is less then 0.5 or higher if greater than or equal to 0.5 |
| TendInwards | The Digit which is greater when the value is less then 0.5 or lower if greater than or equal to 0.5 |
- *1 : The default case.
- *2 : uses Math.Round internally and this will usually be adequate.
- *3 : uses Math.Floor internally.
- *4 : uses Math.Ceiling internally.
To specify a digitation policy simply supply its name, such as DigitationPolicy.TendUpwards.
The difference between these cases can sometimes be subtle so it is recommended that you experiment to see which is best for your particular requirements with the data you are processing.
Functions are available for converting to and from POCO types and DU cases. See the overview documentation for more information about these.
Exception-free processing versions - FailSafe, Option, and Result - of some functions are available. See the overview documentation for more information about these.
