Mike Cowlishaw - Wikipedia
Cowlishaw has worked on aspects of decimal arithmetic; his proposal for an improved Java BigDecimal class (JSR 13) is now included in Java 5.0, and in 2002, he invented a refinement of Chen–Ho encoding known as densely packed decimal encoding.

I’m Mike Cowlishaw, a Fellow of the Royal Academy of Engineering, sometime Visiting Professor at the Department of Computer Science at the University of Warwick, and Editor of the IEEE 754 2008 & 2019 (ISO/IEC 60559) floating-point arithmetic standards from 2006 through 2023.
A Summary of Densely Packed Decimal encoding - Speleotrove
The new encoding allows arbitrary-length decimal numbers to be coded efficiently while keeping decimal digit boundaries accessible. This in turn permits efficient decimal arithmetic and makes the best use of available resources such as storage or hardware registers.
Densely packed decimal - Wikipedia
Densely packed decimal is a refinement of this, devised by Mike F. Cowlishaw in 2002, [1] which was incorporated into the IEEE 754-2008 [3] and ISO/IEC/IEEE 60559:2011 [4] standards for decimal floating point.

Decimal arithmetic is the norm in human calculations, and human-centric applications must use a decimal floating-point arithmetic to achieve the same results.

Mr. Michael (Mike) F. Cowlishaw | IT History Society
Cowlishaw's decimal arithmetic specification formed the proposal for the decimal parts of the IEEE 754 standard, as well as being followed by many implementations, such as Python and SAP Netweaver. His decNumber decimal package is also available as open source under several licenses and is now part of GCC, and his proposals for decimal hardware ...
Mike Cowlishaw - biography - Speleotrove
From 1999 through 2009, he worked on new decimal arithmetic packages (including IBM’s BigDecimal class for Java and the decNumber C library), invented the Densely Packed Decimal encoding, and helped specify new decimal hardware architecture.
