Description

Functions for reading, writing and converting IEEE 754 floating point numbers.

Conversions use STUArray and the ST monad to reinterpret bytes and get what we assume to be the IEEE 754 binary representation of single and double precision floating point numbers.

Synopsis

Big-endian reads

getFloat32be :: Get Float Source

Read a 32-bit float in big endian format

getFloat64be :: Get Double Source

Read a 64-bit float in big endian format

Little-endian reads

getFloat32le :: Get Float Source

Read a 32-bit float in little endian format

getFloat64le :: Get Double Source

Read a 64-bit float in little endian format

Host-endian, unaligned reads

getFloat32host :: Get Float Source

Read a 32-bit float in native host order and host endianness

getFloat64host :: Get Double Source

Read a 64-bit float in native host order and host endianness

Little-endian writes

putFloat32le :: Putter Float Source

Write a 32-bit float in little endian format

putFloat64le :: Putter Double Source

Write a 64-bit float in little endian format

Big-endian writes

putFloat32be :: Putter Float Source
