summary

summary(x)

Return a string giving a brief description of a value. By default returns string(typeof(x)). For arrays, returns strings like "2x2 Float64 Array".

Examples

In the Julia programming language, the function summary(x) is used to generate a brief description of a value. By default, it returns a string representation of the type of the value x. For arrays, it provides a descriptive string.

Get the summary of a numeric value:
```
julia> summary(42)
"Int64"
```
This example returns a summary string representing the type of the numeric value 42.
Get the summary of a string:
```
julia> summary("Hello, Julia!")
"String"
```
It returns a summary string indicating the type of the given string.
Get the summary of an array:
```
julia> arr = [1, 2, 3, 4, 5];
julia> summary(arr)
"5-element Vector{Int64}"
```
This example returns a summary string representing the type and size of the array.

Custom type summary:

julia> struct Person
          name::String
          age::Int
      end
julia> summary(Person("Alice", 30))
"Person"

It returns a summary string representing the type of the custom-defined Person object.

Common mistake example:

julia> summary(3.14)
"Float64"

In this example, the summary function correctly returns the summary string representing the type of the floating-point number 3.14. However, a common mistake is to expect the summary to include more detailed information such as the decimal precision. The summary function provides a brief description and does not include such details.
