How to Get Datatype In Julia?

2 minutes read

To get the data type of a variable or value in Julia, you can use the typeof() function. This function will return the type of the specified object, allowing you to determine whether it is an integer, float, string, array, or any other data type. Here is an example of how to use the typeof() function in Julia:

1
2
3
4
5
6
7
8

x = 5
println(typeof(x))  # This will print "Int64"

y = 3.14
println(typeof(y))  # This will print "Float64"

z = "Hello, world!"
println(typeof(z))  # This will print "String"


By using the typeof() function, you can easily identify the data type of any variable or value in your Julia code.


How to check the datatype of a floating point number in Julia?

In Julia, you can use the typeof() function to check the datatype of a floating point number. Here's an example code to check the datatype of a floating point number:

1
2
3
4
5
6
7

# Define a floating point number
float_num = 3.14

# Check the datatype of the floating point number
datatype = typeof(float_num)

println(datatype)


When you run this code, it will output:

1

Float64


This means that the datatype of the floating point number 3.14 is Float64 in Julia.


How to access the datatype of a missing value in Julia?

In Julia, missing values are of the type Missing. To access the data type of a missing value, you can simply use the typeof() function. Here is an example:

1
2

missing_value = missing
println(typeof(missing_value))  # Output: Missing


In this example, the typeof() function is used to determine the data type of the missing_value, which is of the type Missing.


How to extract the datatype of a symbol in Julia?

In Julia, you can use the typeof() function to extract the data type of a symbol. Here's an example:

1
2
3
4

x = 10
y = "hello"
println(typeof(x))  # Output: Int64
println(typeof(y))  # Output: String


In this example, typeof(x) will return Int64 because the data type of the variable x is an integer, while typeof(y) will return String because the data type of the variable y is a string.


How to ascertain the datatype of a datetime object in Julia?

To ascertain the datatype of a datetime object in Julia, you can use the typeof() function. For example, if you have a datetime object dt, you can use typeof(dt) to determine its data type.


Here is an example demonstrating how to ascertain the datatype of a datetime object in Julia:

1
2
3
4
5
6
7

using Dates

# Create a datetime object
dt = DateTime("2021-10-10T10:10:10")

# Determine the datatype of the datetime object
println(typeof(dt))


Running this code will output DateTime as the datatype of the dt object, indicating that it is a datetime object in Julia.
