Julia Exponential Function
Julia Exponential Root is used to find the exponent of a number.
In this tutorial, we will learn how to use the exponential function, exp() with examples.
If the argument to the exponential function is near zero and you require an accurate computation of the exponential function, use expm1(x) function.
Example 1 – Julia Exponential Function
Exponential function with Integer
julia> x = 2 2 julia> exp(x) 7.38905609893065
Exponential function with Floating Point Numbers
julia> x = 3.5241 3.5241 julia> exp(x) 33.92322896714677
Exponential function with Complex Numbers
julia> x = 3 + 5im 3 + 5im julia> exp(x) 5.697507299833739 - 19.26050892528742im
Example 2 – Julia Exponential Function – expm1
The accurate value of an exponential function is calculated with expm1() function. In the following example, we compared the accurate value of the exponential of an extremely small value (near to zero) with exp() function.
julia> x = 0.000000001 1.0e-9 julia> exp(x) 1.000000001 julia> expm1(x) 1.0000000005000001e-9
Conclusion
In this Julia Tutorial, we learned about Julia Exponential Function and its usage with the help of example scripts.
