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, inf or -inf are not considered equal to themselves because they represent a set of numbers.
NaN and Infinity are not equal to themselves
