exp
exp(x)
Compute $e^x$.
Examples
julia> exp(2)
7.3890560989306495The exp function in Julia computes the exponential function, which raises Euler's number e to the power of x. Here are some common examples of its use:
-
Compute exponential value:
julia> exp(1) 2.718281828459045This example calculates the value of
e^1. -
Calculate exponential value for negative numbers:
julia> exp(-0.5) 0.6065306597126334It calculates the exponential value for negative numbers, in this case,
e^(-0.5). - Use with variables:
julia> x = 0.8; julia> exp(x) 2.225540928492468It can be used with variables, allowing dynamic computation of the exponential function.
Common mistake example:
julia> exp("Hello")
ERROR: MethodError: no method matching exp(::String)In this example, the input argument "Hello" is of type String, which is not compatible with the exp function. Ensure that the argument is of a numeric type when using exp.
