Determine the supertype of a type in Julia

Julia | Example of supertype() function: In this tutorial, we are going to learn how to determine the supertype of a type (datatype) in the Julia programming language?

To determine the supertype of a type – we use the supertype() function, it accepts a data type and returns the concrete supertype of the given type.

Example:

# Julia example to determine the 
# supertype of a type in Julia

println("supertype(Bool): ", supertype(Bool))
println("supertype(Char): ", supertype(Char))
println("supertype(String): ", supertype(String))
println()

println("supertype(Int8): ", supertype(Int8))
println("supertype(Int16): ", supertype(Int16))
println("supertype(Int32): ", supertype(Int32))
println("supertype(Int64): ", supertype(Int64))
println()

println("supertype(Float16): ", supertype(Float16))
println("supertype(Float32): ", supertype(Float32))
println("supertype(Float64): ", supertype(Float64))
println()

Output

supertype(Bool): Integer
supertype(Char): AbstractChar
supertype(String): AbstractString

supertype(Int8): Signed
supertype(Int16): Signed
supertype(Int32): Signed
supertype(Int64): Signed

supertype(Float16): AbstractFloat
supertype(Float32): AbstractFloat
supertype(Float64): AbstractFloat
