Package org.orekit.utils

Class AccurateFormatter

java.lang.Object

org.orekit.utils.AccurateFormatter

All Implemented Interfaces:

Formatter

public class AccurateFormatter
extends Object
implements Formatter

Formatter used to produce strings from data with high accuracy.

When producing test output from computed data, we want the shortest decimal representation of a floating point number that maintains round-trip safety. That is, a correct parser can recover the exact original number.

For efficiency, this class uses the Ryū algorithm for producing shortest string representation with round-trip safety.
