FloatEntry (Java SE 25 & JDK 25)
Description: declaration: module: java.base, package: java.lang.classfile.constantpool, interface: FloatEntry
Keywords: java.lang.classfile.constantpool.FloatEntry interface

# Interface FloatEntry

All Superinterfaces:
  `AnnotationConstantValueEntry, ConstantValueEntry, LoadableConstantEntry, PoolEntry`

public sealed interface FloatEntry extends AnnotationConstantValueEntry, ConstantValueEntry
Models a `CONSTANT_Float_info` structure, or a `float` constant, in the constant pool of a `class` file.

The use of a `FloatEntry` is modeled by a `float`. Conversions are through `ConstantPoolBuilder.floatEntry(float)` and `floatValue()`. In the conversions, all NaN values of the `float` may or may not be collapsed into a single "canonical" NaN value.

See Java Virtual Machine Specification:
  4.4.4 The `CONSTANT_Integer_info` and `CONSTANT_Float_info` Structures
