"A Pocket Calculator for Computer Science Professionals - This compact, yet powerful pocket calculator is designed for technical professionals working in computer science and digital electronics. Boolean operations and bit manipulation are some of its capabilities" (PDF). Hewlett-Packard Journal. 34 (5).
The HP Voyager series calculator are keystroke programmable, meaning that it can remember and later execute sequences of keystrokes to solve particular problems of interest to the user. These keystroke programs, in addition to performing any operation normally available on the keyboard, can also make use of conditional and unconditional ...
HP's first scientific calculator, HP-35. With this in mind, HP built the HP 9100 desktop scientific calculator. This was a full-featured calculator that included not only standard "adding machine" functions but also powerful capabilities to handle floating-point numbers, trigonometric functions, logarithms, exponentiation, and square roots.
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
HP 48G calculator, uses RPL RPL [5] is a handheld calculator operating system and application programming language used on Hewlett-Packard 's scientific graphing RPN (Reverse Polish Notation) calculators of the HP 28 , 48 , 49 and 50 series, but it is also usable on non-RPN calculators, such as the 38 , 39 and 40 series.
A 32-bit register can store 2 32 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. With the two most common representations, the range is 0 through 4,294,967,295 (2 32 − 1) for representation as an binary number, and −2,147,483,648 (−2 31) through 2,147,483,647 (2 31 − 1) for representation as two's complement.
For instance, using a 32-bit format, 16 bits may be used for the integer and 16 for the fraction. The eight's bit is followed by the four's bit, then the two's bit, then the one's bit. The fractional bits continue the pattern set by the integer bits. The next bit is the half's bit, then the quarter's bit, then the ⅛'s bit, and so on. For example:
The processor has a 20-bit address bus available to code but due to the presence of the high/low nibble selection bit, only 19 bits are available externally. In both the HP 48S/SX and G/GX series, the Saturn CPU core is integrated as part of a more complex integrated circuit (IC) package.
