By the 17th century, mathematicians generally used decimal fractions with modern notation. It was not, however, until the 19th century that mathematicians separated irrationals into algebraic and transcendental parts, and once more undertook the scientific study of irrationals. In 1872, the publication of the theories of Karl Weierstrass (by his pupil E. Kossak), Eduard Heine, Georg Cantor, and Richard Dedekind was brought about.

The concept of decimal fractions is closely linked with decimal place-value notation; the two seem to have developed in tandem. For example, it is common for the Jain math sutra to include calculations of decimal-fraction approximations to pi or the square root of 2. Similarly, Babylonian math texts used sexagesimal fractions with great frequency. It is likely that the concept of fractional numbers dates to prehistoric times. The Ancient Egyptians used their Egyptian fraction notation for rational numbers in mathematical texts such as the Rhind Mathematical Papyrus and the Kahun Papyrus. Classical Greek and Indian mathematicians made studies of the theory of rational numbers, as part of the general study of number theory.

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. Numbers are most commonly expressed in literal forms like 0b101, 0o13, 0x0A.

Numerators and denominators form fractions, which are comprised of two integers. The number on top is the numerator; the number on the bottom is the denominator. The numerator, the top number, shows how many parts we have.

For mechanical devices, the symbol appeared on the keyboard of the Remington Standard typewriter (c. 1886) but was not used on the keyboards used for typesetting. It appeared in many of the early teleprinter codes and from there was copied to ASCII, which made it available on computers and thus caused many more uses to be found for the character. The symbol was introduced on the bottom right button of touch-tone keypads in 1968, but that button was not extensively used until the advent of large scale voicemail (PBX systems, etc.) in the early 1980s. Consider the numbers having incrementally largest numbers of letters. This gives the sequence 1, 3, 11, 13, 17, 23, 73, 101, 103, 111, 113, 117, 123, 173, 323, 373, ...
