Euler 常量 ℇ

Euler Constant was discovered by a genius mathematician in 1735. It’s used in various analytical formulas and number theory. Math scientists still argue if this constant is a rational, algebraic or transcendental number. It equals approximately 0,577. I doubt that mathematicians will forgive us for such an imprecise description, since after the comma there come thousands of signs, which we’re not going to reproduce.

Anyway, to talk about Euler Constant, you can use this symbol ℇ from Unicode. The value is often expressed with 「gamma」 – 𝛄 or 「C」 – c .

符号 「Euler 常量」 包含在 「字母式符号」 块的 「字母符號」 子块中，并在1993年作为Unicode版本1.1的一部分获得批准。
