Julia | NaN/Nan64 Constant

Nan / Nan64 is a constant of the Float64 type in Julia programming language, it represents "not-a-number" value.

Syntax:

    NaN
    NaN64

Example:

In this example, we are taking two variables x and y and assigning them with NaN and NaN64. We are printing the values and types of x and y using println() function and typeof() function. We are also comparing the NaN and NaN64.

# Julia example of NaN and NaN64

x = NaN
y = NaN64

println("x: ", x)
println("y: ", y)

println("typeof(x): ", typeof(x))
println("typeof(y): ", typeof(y))

# checking whether NaN and NaN64 are same
println("NaN==NaN: ", NaN==NaN64)

Output

x: NaN
y: NaN
typeof(x): Float64
typeof(y): Float64
NaN==NaN: false
