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.
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 ...
Ruby: the built-in Bignum integer type is of arbitrary precision. The BigDecimal class in the standard library module bigdecimal has user definable precision. Scheme: R 5 RS encourages, and R 6 RS requires, that exact integers and exact rationals be of arbitrary precision. Scala: Class BigInt and Class BigDecimal. Seed7: bigInteger and bigRational.
Starting with Ruby version 1.9.2 (released on 18 August 2010), the bug with year 2038 is fixed, [16] by storing time in a signed 64-bit integer on systems with 32-bit time_t. [17] Starting with NetBSD version 6.0 (released in October 2012), the NetBSD operating system uses a 64-bit time_t for both 32-bit and 64-bit
Arithmetic underflow can occur when the true result of a floating-point operation is smaller in magnitude (that is, closer to zero) than the smallest value representable as a normal floating-point number in the target datatype. [1] Underflow can in part be regarded as negative overflow of the exponent of the floating-point value. For example ...
In October, iQIYI participated in the Busan Film Festival, signing exclusive rights to nearly 100 South Korean titles. [11] On November 19, 2014, Xiaomi and Shunwei Capital invested $300 million in iQIYI for about 10 percent to 15 percent of the site, while Baidu invested an additional $100 million and held about 80 percent.
Integer overflow is a special case of arithmetic overflow. I don't see the need for two articles. Derek farn 08:54, 10 October 2006 (UTC) I think this makes sense as two different articles. Integer overflow is of particular interest in computer security and is reference from the computer security page.
Performs software interrupt #1 if executed when not using in-circuit emulation. [p] 3 UMOV r/m, r8 0F 10 /r: User Move – perform data moves that can access user memory while in In-circuit emulation HALT mode. Performs same operation as MOV if executed when not doing in-circuit emulation. [q] UMOV r/m, r16/32 0F 11 /r UMOV r8, r/m 0F 12 /r
