Financial calculator Financial calculator A financial calculator or business calculator is an electronic calculator that performs financial functions commonly needed in business and commerce communities (simple interest, compound interest, cash flow, amortization, conversion, cost/sell/margin, etc). It has standalone keys for many financial calculations and functions, making such calculations more direct than on standard calculators. It may be user programmable, allowing the user to add functions that the manufacturer has not provided by default. Examples of financial calculators are the HP 12C, HP-10B and the TI BA II. Wide number of graphics calculators like Casio fx-9860GII, Texas Instruments TI-89 Titanium, Hewlett Packard HP-48GII,
Calculator subtract, and divide, and its output device was a paper tape. The electronic calculators of the mid-1960s were large and heavy desktop machines due to their use of hundreds of transistors on several circuit boards with a large power consumption that required an AC power supply. There were great efforts to put the logic required for a calculator into fewer and fewer integrated circuits (chips) and calculator electronics was one of the leading edges of semiconductor development. U.S. semiconductor manufacturers led the world in large scale integration (LSI) semiconductor development, squeezing more and more functions into individual integrated circuits. This
