The following example uses the IFT function to pop an object from the bottom of the stack and, if it is equal to 1, replaces it with "One": « 1 == "One" IFT » The following example uses the IFTE function to pop an object from the bottom of the stack and, if it is equal to 1, replaces it with "One".
C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. [1] [2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions. Most of these functions are also ...
Recognizing that their Numerical Recipes books were increasingly valued more for their explanatory text than for their code examples, the authors significantly expanded the scope of the book, and significantly rewrote a large part of the text. They continued to include code, still printed in the book, now in C++, for every method discussed. [5]
bc first appeared in Version 6 Unix in 1975. It was written by Lorinda Cherry of Bell Labs as a front end to dc, an arbitrary-precision calculator written by Robert Morris and Cherry. dc performed arbitrary-precision computations specified in reverse Polish notation. bc provided a conventional programming-language interface to the same capability via a simple compiler (a single yacc source ...
The original code from the Unix Programming Environment book, including hoc. Source code of hoc from Bell Labs, released as free software. This is the Research Unix version, slightly improved over the one in the book. Plan9 version of hoc released under the Lucent Public License. This version is slightly different from the Research Unix version ...
dc (desk calculator) is a cross-platform reverse-Polish calculator which supports arbitrary-precision arithmetic. [1] It was written by Lorinda Cherry and Robert Morris at Bell Labs. [2] It is one of the oldest Unix utilities, preceding even the invention of the C programming language. Like other utilities of that vintage, it has a powerful set ...
It was specifically designed for use by computer programmers, to assist in debugging. It is a member of the HP Voyager series of programmable calculators. It was the only programmer's calculator ever produced by HP, though many later HP calculators have incorporated most of the 16C's functions.
Output from the program can be in the form of scrolling or located text, graphs, or by writing data to lists and matrices in the calculator memory. Casio also makes label printers which can be used with rolls of paper for the Casio BASIC calculators. [ 2 ]
