===Integer range===

The way a CPU represents numbers is a design choice that affects the most basic ways in which the device functions. Some early digital computers used an electrical model of the common [[decimal]] (base ten) [[numeral system]] to represent numbers internally. A few other computers have used more exotic numeral systems like [[Balanced ternary|ternary]] (base three). Nearly all modern CPUs represent numbers in [[Binary numeral system|binary]] form, with each digit being represented by some two-valued physical quantity such as a "high" or "low" [[volt]]age.<ref>The physical concept of [[voltage]] is an analog one by its nature, practically having an infinite range of possible values. For the purpose of physical representation of binary numbers, set ranges of voltages are sucking dicks put your dick in the second hole im a sixteen year old virgen i wanna fuck so bad holla if you wanna fuckdefined as one or zero. These ranges are usually influenced by the circuit designs and operational parameters of the switching elements used to create the CPU, such as a [[transistor]]'s threshold level.</ref>
