The HP 30b (model NW238AA, internally referred to as "Big Euro", "Mid Euro", or "Fox") is a programmable financial calculator produced by HP, introduced on January 7, 2010. Serving as a more sophisticated follow-up to the HP 20b, it boasts a dual-line alphanumeric screen and supports various input formats such as Reverse Polish Notation, Algebraic, and Chain algebraic entry, with a display capable of showing twelve digits.
Equipped with an ARM processor, the HP 30b offers certain scientific capabilities that are rare among financial calculators. It notably incorporates the Black-Scholes equation for pricing options and includes functions for calculating the Modified Internal Rate of Return and Financial Management Rate of Return, which were unprecedented features in its category.
This model is not authorized for use during prominent professional examinations like the CFA Charter exam.
HP 40b
The HP 40b was intended as an upgraded iteration of the 30b, featuring enhancements such as a USB interface, programmability via PC, and the ability to function as an external PC keypad. However, only a limited number of prototype units were manufactured.
WP 31S, WP 34S and WP 34C
The firmware of the HP 30b can be replaced ("flashed") through connection to a computer. Utilizing this capability, developers created the WP 34S firmware in 2011, converting the device into a fully programmable scientific calculator. Both the firmware and its documentation are available for free download, while optional serial cables and keypad overlays can be purchased separately. Additionally, the WP 34S was offered commercially.
A version supporting complex numbers is known as WP 34C (released in 2015), whereas WP 31S (2014) represents a streamlined adaptation of the WP 34S. The community-driven WP 43S, built on SwissMicros DM42 hardware, continues this development lineage.
