Compute $e^x$.


julia> exp(2)

The 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:

  1. Compute exponential value:

    julia> exp(1)

    This example calculates the value of e^1.

  2. Calculate exponential value for negative numbers:

    julia> exp(-0.5)

    It calculates the exponential value for negative numbers, in this case, e^(-0.5).

  3. Use with variables:
    julia> x = 0.8;
    julia> exp(x)

    It 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.
