Equal Numbers
| Type | Script block |
| Collider | None |
| Folder | Math |
| Ports | |
|---|---|
| Inputs | Num1 Num2 |
| Outputs | Num1 = Num2 |
Outputs True if both number inputs are equal, and false if they are not.
Notes
- The numbers do not have to be actually equal to be considered equal, they have to be close enough.
0.001 is equal to 0
- If high precision is required, the following script can be used:
Does not have the same issue as the example above
- You can check whether a number is valid by checking whether it is equal to itself.
nan,infor-infare not considered equal to themselves because they represent a set of numbers.
NaN and Infinity are not equal to themselves
