If I execute 3*0.1, Julia prints the value as 0.30000000000000004. I believe the inaccuracy is caused by machine precision, but it doesn’t seem useful to me that Julia would display this. I also note that I have never encountered this kind of issue working with numbers greater than 1. What’s the cau…

Have you seen http://0.30000000000000004.com/ ? [image] aahaselgrove: Eg. (in C, what I would expect) That seems to print 2.9999999999999999e-01 (which Julia also does with @printf): julia> using Printf julia> @printf "%1.16e\n" .3 2.9999999999999999e-01 Anyway, Julia uses the GRISU (or Ry…
