Julia| NaN / Nan64常数 (Julia | NaN/Nan64 Constant)

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

Nan / Nan64是Julia编程语言中Float64类型的常量，它表示“非数字”值。

Syntax:

句法：

    NaN
NaN64

Example:

例：

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.

在此示例中，我们采用两个变量x和y ，并为其分配NaN和NaN64 。 我们正在使用println()函数和typeof()函数打印x和y的值和类型。 我们还在比较NaN和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

输出量

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