About this product
Product Information
The only Hewlett-Packard calculator ever produced specifically for programmers, the HP-16C is a powerful calculator that goes far beyond that narrow realm, as evidenced by its use long after HP produced it in the 1980s. This designation makes the model attractive to collectors, programmers, and mathematicians alike. The HP-16C is part of the company‘s HP Voyager Series, able to display numbers in decimal, binary, octal and hexadecimal characters, as well as convert number bases. For more complex calculations, the HP-16C‘s display can be programmed to shift it left and right, which also allows for consistency between the calculator and the user‘s computer. Beyond programming, the HP-16C performs basic arithmetic, reciprocal and square root calculations, and more. Its HP Nut processor also features continuous memory, which means it retains its memory when the calculator is turned off.Product Identifiers

My "Go-to" Calculator.
Disclaimer: I am a calculator "nut" and I love HP. That said, IMO, HP made a big mistake when they discontinued this calculator and they should consider reintroducing it with a larger, multi-line, pixelated display. The display limitations are really my only ding on this unit but, that was the technology at the time. I rated the HP 16c as a "good value" but, that is subjective. I found one for a "reasonable" price but, I had to search for several weeks to find one in near mint and with original book for a price I was willing to pay. They are considered a must-have by HP calculator collectors so, sellers are asking a bundle. Look for "auctions" and "make an offer" to get a fair price. For me, converting between Hex, Oct and Bin are second nature but converting to Dec is a pain to do manually. The HP 16c makes this instantaneous. Also working with 2's compliment numbers is a breeze. A huge help with logical design, as well. And it's just the coolest in the geekiest possible way. :)Verified purchase: Yes

Not sure why this isn't made anymore!
I am impressed with the functionality of this calculator and am surprised that HP (or another mfgr) doesn't still make this or one similar to it... Even in 2018, a standalone unit like this has its advantages over a smartphone app that emulates the HP 16C! This will certainly come in handy when I go back to college for computer science,Verified purchase: Yes
