Julia | Rational Numbers

Julia programming language supports a rational number type to represent the exact ratios of the integer numbers.

To define a rational number, we use the // operator.

Syntax:

    2//3

Example:

# Rational Numbers in Julia

println(1//2)
println(1//2 + 2//3)
println("typeof(1//2): ", typeof(1//2))
println()

# other representation
println("1//2: ", 1//2)
println("2//4: ", 2//4)
println("8//2: ", 8//2)
println()

println("-1//2: ", -1//2)
println("-2//4: ", -2//4)
println("-8//2: ", -8//2)
println()

println("1//-2: ", 1//-2)
println("2//-4: ", 2//-4)
println("8//-2: ", 8//-2)
println()

println("-1//-2: ", -1//-2)
println("-2//-4: ", -2//-4)
println("-8//-2: ", -8//-2)
println()

Output

1//2
7//6
typeof(1//2): Rational{Int64}

1//2: 1//2
2//4: 1//2
8//2: 4//1

-1//2: -1//2
-2//4: -1//2
-8//2: -4//1

1//-2: -1//2
2//-4: -1//2
8//-2: -4//1

-1//-2: 1//2
-2//-4: 1//2
-8//-2: 4//1
