getF64Decoder

const getF64Decoder: (config?) => FixedSizeDecoder<number, 8>

Returns a decoder for 64-bit floating-point numbers (f64).

This decoder deserializes f64 values from 8 bytes. Some precision may be lost during decoding due to floating-point representation.

For more details, see getF64Codec.

Parameters

Parameter	Type	Description
`config?`	`NumberCodecConfig`	Optional configuration to specify endianness (little by default).

A FixedSizeDecoder<number, 8> for decoding f64 values.

Decoding an f64 value.

const decoder = getF64Decoder();
const value = decoder.decode(new Uint8Array([0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xf8, 0xbf])); // -1.5
