# How to Get Datatype In Julia?

To get the datatype of a variable in Julia, you can use the `typeof()` function. For example, if you have a variable `x` and you want to know its datatype, you can simply call `typeof(x)`. This will return the datatype of the variable `x`, which can be any of the primitive datatypes such as `Int64`, `Float64`, `String`, etc. You can also use the `typeof()` function to get the datatype of an expression or a value by passing it as an argument to the function.

## How to get datatype in Julia for booleans?

In Julia, you can get the datatype for booleans using the `typeof()` function.

For example, to get the datatype for a boolean variable `b`, you can use the following code:

 ```1 2 ``` ```b = true println(typeof(b)) ```

This will output `Bool`, which is the datatype for booleans in Julia.

## What is the output of getting datatype in Julia?

In Julia, the output of getting the datatype of a variable or value is the type of the variable or value. For example, if you have a variable `x` with the value `5`, using the `typeof()` function will output `Int64`, indicating that `x` is an integer of 64 bits.

## How to get datatype in Julia for ranges?

In Julia, you can use the `eltype()` function to get the data type of elements in a range. Here is an example:

 ```1 2 3 ``` ```r = 1:10 data_type = eltype(r) println(data_type) ```

This will output the data type of the elements in the range `1:10`, which is `Int64` in this case.

You can also specify the data type when creating a range by using the `::` syntax. For example:

 ```1 2 3 ``` ```r = 1:10::Float64 data_type = eltype(r) println(data_type) ```

This will output `Float64` as the data type of elements in the range `1.0:10.0`.
