U+215F Fraction Numerator One

U+215F was added in Unicode version 1.1 in 1993. It belongs to the block U+2150 para U+218F Number Forms in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Other Number and is commonly used, that is, in no specific script. The codepoint has the numeric value 1.

The glyph is a fraction composition of the glyphs Digit One, Fraction Slash. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+215F forms with similar adjacent characters prevents a line break inside it.

El Wikipedia tiene la siguiente información acerca de este punto de código:

Una fracción unitaria es un número racional escrito en forma de fracción cuyo numerador es 1 y el denominador es un número entero positivo. Las fracciones unitarias son, por tanto, los inversos de los enteros positivos, $\frac{1}{n}$ . Ejemplos: $\frac{1}{1}, \frac{1}{2}, \frac{1}{3}, \frac{1}{42}$ , etc.
Las sumas parciales $\frac{1}{1} + \frac{1}{2} + \frac{1}{3} + \dots + \frac{1}{n}$ generan la serie armónica, y se va acercando a logaritmo natural ln(n) + γ a medida que n crece. Así que la suma de todas las fracciones unitarias es infinita.
