Notes: a The generic 56 function scientific calculator is sold under numerous brand names in several distinct case styles. For example, this calculator is sold as the Radio Shack EC4038, DATEXX DS-700, DigiTech ATC-517 and ATC-828, Tozai ATC-828, Victor 930, Sentry CA565, LeWorld 250, and Canon F-502 (billed as having 136 functions). b Polynomial approximations used to compute trigonometric functions. c I believe this is an APF Mark 8501 manufactured for Radio Shack. d A model of the HP Spice series. e A model of the HP Voyager series. f A model of the HP Pioneer series. g The last digit is indeed different from that of more common (later?) versions of the Casio fx-7000G. h The Omron SR-10 produces a different result depending on whether or not the display format switch is in the EXP (1.2199423E01) or FLT (14.541191) position. 1
The Citizen SRP-320G, Durabrand 828 (older SC-828 version), and other related low-end graphing calculators do not compute arcsin in degrees, even when in degrees mode, as part of a formula such as the forensics formula. The arcsin step of the forensics algorithm must be computed as "sin-1 Ans". j I believe this device uses true floating point for its transcendental calculations, instead of the traditional BCD (Binary Coded Decimal) of most calculators. k The Sharp PC-1001 produces a different result depending on whether or not the display format switch is in the EXP (9.0000606185) or FLOAT (9.0039554305) position. 37 m Unexplained different results from different contributors. n There are two versions of the Durabrand 828, the older SC-828 version and the newer SC-1376 version.
