oftype

oftype(x, y)

Convert y to the type of x (convert(typeof(x), y)).

Examples

In the Julia programming language, the function oftype(x, y) is used to convert y to the type of x using the convert function (convert(typeof(x), y)). Here are some examples of its usage:

1. Convert an integer to a float:

   julia> oftype(3.14, 5)
   5.0

   This example converts the integer 5 to a float, matching the type of 3.14.

2. Convert a string to an integer:

   julia> oftype(10, "42")
   42

   Here, the string "42" is converted to an integer, matching the type of 10.

3. Convert an array of integers to an array of floats:

   julia> oftype([1, 2, 3, 4], Float64)
   4-element Array{Float64,1}:
   1.0
   2.0
   3.0
   4.0

   This example converts each element of the array [1, 2, 3, 4] to a float, resulting in a new array of type Float64.

Common mistake example:

julia> oftype(2, "hello")
ERROR: MethodError: Cannot `convert` an object of type String to an object of type Int64

In this example, the function oftype fails because it attempts to convert a string "hello" to an integer Int64, which is not possible. Ensure that the types are compatible for successful conversion using oftype.
