Class ToonNumbers

java.lang.Object

io.micronaut.serde.toon.util.ToonNumbers

@Internal
public final class ToonNumbers
extends Object

Formats numbers in the canonical decimal form required by the TOON specification: no leading zeros, no trailing fractional zeros, -0 normalized to 0, NaN/infinite values encoded as null, and scientific notation only outside the 1e-6 <= |n| < 1e21 magnitude window. A BigInteger outside the long range is written as a quoted plain decimal string, so that no precision is lost.

Since:

3.3.0
