Julia | typeof() function

typeof() function is a library function in Julia programming language, it is used to get the concrete type of the given value or variable.

Syntax:

    typeof(x)

Here, x is the value/variable whose data type to be found.

Example:

    typeof(10)
    Int64

    x = 10
    typeof(x)
    Int64

    x = 'A'
    typeof(x)
    Char

    typeof(Int64)
    DataType

Program:

# Example of typeof() function in Julia

# type of values
println("typeof(0): ", typeof(0))
println("typeof(10): ", typeof(10))
println("typeof(-10): ", typeof(-10))
println("typeof(10.23): ", typeof(10.23))
println("typeof('A'): ", typeof('A'))
println("typeof(\"Hello\"): ", typeof("Hello"))
println()

# type of variables
a = 0
b = 10
c = -10
d = 10.23
e = 'A'
f = "Hello"

println("typeof(a): ", typeof(a))
println("typeof(b): ", typeof(b))
println("typeof(c): ", typeof(c))
println("typeof(d): ", typeof(d))
println("typeof(e): ", typeof(e))
println("typeof(f): ", typeof(f))
println()

# type of data type
println("typeof(Bool): ", typeof(Bool))
println("typeof(Int64): ", typeof(Int64))
println("typeof(Float64): ", typeof(Float64))
println("typeof(Char): ", typeof(Char))
println("typeof(String): ", typeof(String))
println()

Output

typeof(0): Int64
typeof(10): Int64
typeof(-10): Int64
typeof(10.23): Float64
typeof('A'): Char
typeof("Hello"): String

typeof(a): Int64
typeof(b): Int64
typeof(c): Int64
typeof(d): Float64
typeof(e): Char
typeof(f): String

typeof(Bool): DataType
typeof(Int64): DataType
typeof(Float64): DataType
typeof(Char): DataType
typeof(String): DataType
