+33653 Depends on the context.
It can mean the number 2.71828...
If it's in a computer program in the form, say, 5.2e4 it means "times ten to the power of" i.e. 5.2e4 is 5.2*10^4
.
The number e is a mathematical constant that is the base of the natural logarithm.
If e^y=x then ln(x)= y with other words the : e^(ln(x))=x is always true
It is approximately equal to 2.71828 and it is the limit of :
lim((1+1/n)^n , n=inf)=e
Simplier it is : 1 + 1/1 + 1/2 + 1/(2*3) + 1/(2*3*4) + 1/(2*3*4*5) + .. 1/(n!) while n reaches infinity .
Also if you want to know e^x is :
1 + x + (x^2)/2 + (x^3)/(2*3) + (x^4)/(2*3*4) + (x^5)/(2*3*4*5) + .. (x^n)/(n!) while n reaches infinity .
EDIT : I wanted to reply to the one who questioned but I made a mistake
