Numeric comparison difficulty in R
I'm using R 2.15.2 and found something like an unusual but serious error in R inequality operator.
> 0.015 -0.005
[1] 0.01
> 0.015 - 0.005 == 0.01
[1] FALSE
> 0.025 - 0.005 == 0.02
[1] TRUE
Is this possible?
it only happens when I compare 0.015 - 0.005 with 0.01.
Any ideas?
Try this with your computer and see this really happens!
Thanks, then what should I do wit inequality?
> 0.015 - 0.005 < 0.01
[1] TRUE
> 0.025 - 0.005 < 0.02
[1] FALSE
