getting an NaN output

[serene orchid]

im getting an NaN output trying to do a small calculation lab...can anyone tell me what im doing wrong here?

[rich ridge]

are you dividing 0.0/0.0?

[serene orchid]

no

let me check

this is the input file

is that whats wrong?

[violet bay]

You're probably dividing by zero

./run ```java
System.out.println(0.0/0.0);

Here is your java(15.0.2) output @violet bay

NaN

i see

so if theres one instance of that it just overrides the rest of the equations needed in the output?

[violet bay]

Yeah, NaN is a bit viral

But you can check for it with Double.isNaN(...)

./run ```java
System.out.println(Double.isNaN(1.0/0.0));
System.out.println(Double.isNaN(0.0/0.0));

Here is your java(15.0.2) output @violet bay

false
true

./run ```java
double x = 0.0/0.0;
double y = x + 45.0;
double z = y * 3.0;
System.out.println(z);

NaN

[violet bay]

./run ```java
double x = 0.0/0.0;
if (x == x) {
System.out.println("Equal");
}
else {
System.out.println("Not equal");
}
