Description
Returns e^v.
(number) = math.exp(v)
Math.E is a constant that represents Euler's number, the base of the natural logarithm, approximately 2.71828.
Lua does not have a direct equivalent constant named math.E.
However, you can obtain the value of e in Lua by utilizing the math.exp() function, which calculates e raised to a given power. To get the value of e itself, you would raise e to the power of 1.
Parameters
v: (number) level of exponentiation for e
Return values
Returns (number) result of exponentiation
Example
Here is how to get the value of e in Lua
local e_value = math.exp(1)
print(e_value) -- output will be approximately 2.718281828459
