Utilities for BER floating‐point encoding and decoding.

== Synopsis

Declared in `<balber_berutil.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
struct BerUtil_FloatingPointImpUtil;
----

== Description

This component‐private utility `struct` provides a namespace for a suite of functions used by `BerUtil` to implement BER encoding and decoding operations for floating point number values. Within the definition of this `struct`:

* *the specification*: > Refers to the August 2015 revision of the ITU‐T Recommendation X.690

* *the floating point specification*: > Refers to the 2008 revision of the IEE 754 Standard for > Floating‐Point Arithemtic.
