Calculator for example, solve quadratic equations symbolically. The first graphing calculator was the Casio fx-7000G released in 1985. The two leading manufacturers, HP and TI, released increasingly feature-laden calculators during the 1980s and 1990s. At the turn of the millennium, the line between a graphing calculator and a handheld computer was not always clear, as some very advanced calculators such as the TI-89, the Voyage 200 and HP-49G could differentiate and integrate functions, solve differential equations, run word processing and PIM software, and connect by wire or IR to other calculators/computers. The HP 12c financial calculator is still produced. It was
Programmable calculator now available. It is installed via a cable or IrDA connection with a computer. RPL is a special Forth-like programming language used by Hewlett- Packard in its high range devices. The first device with RPL calculator was the HP-28C released in 1987. The language PPL was introduced with the HP Prime calculator and is much like Pascal An on-board (i.e. right on the calculator) assembler for TI 89 and related calculators was announced and released in 2014. Machine language programming was often discouraged on early calculator models; however, dedicated platform hackers discovered ways to bypass the built-in interpreters on some
