Note: For vertical alignment of text see: Help:Table#Vertical alignment in cells. If there is no global text alignment set in the top line of the table wikitext, then all text is left aligned, except for header cells which are default center aligned.
On 5 January 1975, the 12-bit field that had been used for dates in the TOPS-10 operating system for DEC PDP-10 computers overflowed, in a bug known as "DATE75". The field value was calculated by taking the number of years since 1964, multiplying by 12, adding the number of months since January, multiplying by 31, and adding the number of days since the start of the month; putting 2 12 − 1 ...
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
Function Keys are also heavily used in the BIOS interface. Generally during the power-on self-test, BIOS access can be gained by hitting either a function key or the Del key. In the BIOS keys can have different purposes depending on the BIOS. However, F10 is the de facto standard for save and exit which saves all changes and restarts the system.
Soft wrapping allows line lengths to adjust automatically with adjustments to the width of the user's window or margin settings, and is a standard feature of all modern text editors, word processors, and email clients. Manual soft breaks are unnecessary when word wrap is done automatically, so hitting the "Enter" key usually produces a hard return.
A built-in function, or builtin function, or intrinsic function, is a function for which the compiler generates code at compile time or provides in a way other than for other functions. [23] A built-in function does not need to be defined like other functions since it is built in to the programming language. [24]
Integer overflow can be demonstrated through an odometer overflowing, a mechanical version of the phenomenon. All digits are set to the maximum 9 and the next increment of the white digit causes a cascade of carry-over additions setting all digits to 0, but there is no higher digit (1,000,000s digit) to change to a 1, so the counter resets to zero.
Pointer arithmetic is not part of the PL/I standard, but many compilers allow expressions of the form ptr = ptr±expression. IBM PL/I also has the builtin function PTRADD to perform the arithmetic. Pointer arithmetic is always performed in bytes. IBM Enterprise PL/I compilers have a new form of typed pointer called a HANDLE.
