Floating point arithmetic not producing exact results in Java
I was recently working on a project when I came across a strange bug.
When 2 was subtracted from 65.12 the value was greater (not equal to) 63.12.
Here’s the simplified code:
System.out.println(65.12-2);
And the output in the console:
63.120000000000005
I’m not sure why this is the case and if anyone knows a simple fix/workaround that would be great!
Thanks.
It has to do with the way floating-point values are handled by computers. The recommended text for fully understanding the topic is: What Every Computer Scientist Should Know About Floating-Point Arithmetic
