Comparing doubles [duplicate]

This question already has answers here: Is this a good way to compare two numbers? (2 answers) Closed 9 years ago. I need to compare to double variables like this if (distance <= radius) both distance and radius are doubles and I remember in class how to use epsilon comparisons for checking equality but how […]
