This character is a Lowercase Letter and is commonly used, that is, in no specific script. El carácter es también conocido como error y natural exponent.
The glyph is a font version of the glyph Latin Small Letter E. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+212F forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

The number e is a mathematical constant approximately equal to 2.71828 that is the base of the natural logarithm and exponential function. It is sometimes called Euler's number, after the Swiss mathematician Leonhard Euler, though this can invite confusion with Euler numbers, or with Euler's constant, a different constant typically denoted . Alternatively, e can be called Napier's constant after John Napier. The Swiss mathematician Jacob Bernoulli discovered the constant while studying compound interest.
The number e is of great importance in mathematics, alongside 0, 1, π, and i. All five appear in one formulation of Euler's identity and play important and recurring roles across mathematics. Like the constant π, e is irrational, meaning that it cannot be represented as a ratio of integers, and moreover it is transcendental, meaning that it is not a root of any non-zero polynomial with rational coefficients. To 30 decimal places, the value of e is:
