The HP-16C is a pocket calculator that was produced by Hewlett-Packard between 1982 and 1989. 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. ==Features== The 16C can display numbers in hexadecimal, decimal, octal and binary, and convert numbers from one number base to another. To accommodate long binary numbers, the display can be 'windowed' by shifting it left and right. For consistency with the computer the programmer is working with, the word size can be set to different values from 1 to 64 bits. Binary-arithmetic operations can be performed as unsigned, one's complement, or two's complement operations. This allows the calculator to emulate the programmer's computer. A number of specialised functions are provided to assist the programmer, including left- and right-shifting, masking, and bitwise logical operations. Apart from programmer functions, the calculator's abilities are limited to basic arithmetic (and reciprocal and square root),〔(【引用サイトリンク】title=Hewlett-Packard HP-16C )〕 which meant that typical users would also make use of a general scientific calculator. However, it is still far more powerful (though also much more expensive) than contemporary competitors such as the TI LCD Programmer.〔(【引用サイトリンク】title=Texas Instruments LCD Programmer )〕 The base of the 16C features a printed reference chart for many of its functions.〔(【引用サイトリンク】title=Hewlett-Packard 16C aka Voyager PR )〕 The calculator uses the proprietary HP Nut processor produced in a silicon on sapphire process and featured continuous memory, whereby the contents of memory are preserved while the calculator is turned off.〔(【引用サイトリンク】title=HP-16C Owner's Handbook )〕 Though commonplace now, this was still notable in the early 1980s, and is the origin of the "C" in the model name. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HP-16C」の詳細全文を読む スポンサード リンク
