Yes, it would be interesting. I have thought some time ago to make here a series of articles about formulas and algorithms I used in my math lib (after long process of research and testing from many sources). They are rather suitable for microcontrollers and IEEE-754 floating point (both 32 and 64-bit). However, for early BCD based chips used in calculators, suitable algorithms are a bit different and much slower due extremely limited resources, on the contrary very cheap nowadays MCUs have.

Specialized books are still not cheap sources and often even Wikipedia (internet in general) have good enough sources for this purpose...

Today, calculator manufacturers rather keep all used algorithms closed, under intellectual property rights, on the contrary as that was the case in pioneer days. Good resource for advanced research as well are open source CAS libraries.
