HP has never made another calculator specifically for programmers, [2] but has incorporated many of the HP-16C's functions in later scientific and graphing calculators, for example the HP-42S (1988) and its successors. Like many other vintage HP calculators, the HP-16C is now highly sought-after by collectors. [14]
Find a bijection f : A → T such that the cost function: (, ()) is minimized. Usually the weight function is viewed as a square real-valued matrix C, so that the cost function is written down as: , The problem is "linear" because the cost function to be optimized as well as all the constraints contain only linear terms.
Cost function In economics, the cost curve , expressing production costs in terms of the amount produced. In mathematical optimization, the loss function , a function to be minimized.
The immediate execution mode of operation (also known as single-step, algebraic entry system (AES) [7] or chain calculation mode) is commonly employed on most general-purpose calculators. In most simple four-function calculators, such as the Windows calculator in Standard mode and those included with most early operating systems, each binary ...
Numeric-only calculators displayed programming steps as a list of numbers, each number generally mapped to a key on the keyboard, often via row and column coordinates. Encoding functions to the corresponding numeric codes, and vice versa, was left to the user, having to look up the function–code combinations in a reference guide.
The cost function is often defined as a sum of the deviations of key measurements, like altitude or process temperature, from their desired values. The algorithm thus finds those controller settings that minimize undesired deviations. The magnitude of the control action itself may also be included in the cost function.

A financial calculator or business calculator is an electronic calculator that performs financial functions commonly needed in business and commerce communities [1] (simple interest, compound interest, cash flow, amortization, conversion, cost/sell/margin, depreciation etc.).
