Many different representations are possible; all that is needed to formally represent 3 is to inscribe a certain symbol or pattern of symbols three times. A member of any of the further sets of mathematical objects defined in terms of such numbers, such as negative integers, real numbers, and complex numbers. When the set of negative numbers is combined with the set of natural numbers , the result is defined as the set of integers, Z also written Z .

+ and - are allowed at the start of the string to indicate its sign. (In actual code, they "look like" part of the literal, but are actually separate unary operators.) However, the sign can only appear once, and must not be followed by whitespace. The Number constructor contains constants and methods for working with numbers. Values of other types can be converted to numbers using the Number() function. Number values represent floating-point numbers like 37 or -9.25. To total or count; to amount to.I don’t know how many books are in the library, but they must number in the thousands.

JavaScript has some lower-level functions that deal with the binary encoding of integer numbers, most notably bitwise operators and TypedArray objects. Bitwise operators always convert the operands to 32-bit integers. In these cases, after converting the value to a number, the number is then normalized to the given width by first truncating the fractional part and then taking the lowest bits in the integer's two's complement encoding. The mantissa is stored with 52 bits, interpreted as digits after 1.… in a binary fractional number. Therefore, the mantissa's precision is 2-52 (obtainable via Number.EPSILON), or about 15 to 17 decimal places; arithmetic above that level of precision is subject to rounding.

In technical terms, the complex numbers lack a total order that is compatible with field operations. They became more prominent when in the 16th century closed formulas for the roots of third and fourth degree polynomials were discovered by Italian mathematicians such as Niccolò Fontana Tartaglia and Gerolamo Cardano. It was soon realized that these formulas, even if one was only interested in real solutions, sometimes required the manipulation of square roots of negative numbers. It is likely that the concept of fractional numbers dates to prehistoric times.
