In computer science, a lookup table (LUT) is an array that replaces runtime computation with a simpler array indexing operation, in a process termed as direct addressing.The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an "expensive" computation or input/output operation.

The calculator also adopts the same menu based layout as the Classwiz scientific calculators. [ 12 ] [ 13 ] In France, the Classwiz CG Series was introduced in March 2024 with reduced functionality and is known as the Graph Math +.
It is believed that TI increased the speed of HW4 calculators to 16 MHz, though many users disagree about this finding. The measured statistics are closer to 14 MHz. Another difference between HW1 and HW2 calculators is assembly program size limitations. The size limitation on HW2 calculators has varied with the AMS version of the calculator.
The HP Prime Graphing Calculator is a graphing calculator introduced by Hewlett-Packard in 2013 and manufactured by HP Inc. until the licensees Moravia Consulting spol. s r.o. and Royal Consumer Information Products, Inc. took over the continued development, manufacturing, distribution, marketing and support in 2022.
