What value is given to the number e amd what mathematician first used e to designate this value?

Answer 1

The value never truncates, but the first few digits are 2.71828182845904523536.

Quoted from Wiki:
"The first known use of the constant, represented by the letter b, was in correspondence from Gottfried Leibniz to Christiaan Huygens in 1690 and 1691. Leonhard Euler started to use the letter e for the constant in 1727, and the first use of e in a publication was Euler's Mechanica (1736). While in the subsequent years some researchers used the letter c, e was more common and eventually became the standard.

The exact reasons for the use of the letter e are unknown, but it may be because it is the first letter of the word exponential. Another possibility is that Euler used it because it was the first vowel after a, which he was already using for another number, but his reason for using vowels is unknown. It is unlikely that Euler chose the letter because it is his last initial, since he was a very modest man, and tried to give proper credit to the work of others."

Answer 2

# In mathematics,

* e is Euler's number, a transcendental number (approximately equal to 2.718281828459045235360287471352) which is used as the base for natural logarithms.
* One version of a representation of e is e = \sum_{n=0}^\infty {1\over{n!}} = 2.7182818 ...
* Another representation of e is the limit as x approaches infinity of (1 + {1\over{x}})^x.
* A small-caps e is also used to signify y×10x; i.e. 7e8 is 7×108 or 700,000,000.
* E is often used as a digit meaning fourteen in hexadecimal and other positional numeral systems with a radix of 15 or greater.

Answer 3

The numerical value for e (the base of the natural logarithm system) is 2.7182818284590452353602874713527

There are a bunch of sites about the history of the natural logarithms.
