e == 2.718

[james.dill...@gmail.com]

Hi All,

Is there a reason why the irrational constant e seems to be rounded to three decimal places?

julia> e

2.718

julia> e == 2.718

true

Thanks for any info,

This seems like a temporary bug. My most recent build doesn’t behave like this. Hopefully that means it’s been fixed already.

Great!! Thanks.

It doesn't behave that way for me

julia> e
e = 2.7182818284590...

julia> e == 2.718
false

Did you by accident do something like this by accident?
julia> e = 2.718
Warning: imported binding for e overwritten in module Main
2.718

I suspect that Ivar may be right about that accidental assignment. If you did the assignment before using e then you won't get a warning even.

Oops.

That's exactly what happened.

I was running through

yesterday and forgot I ran these lines.

Sorry about that,

No problem. Glad we weren't using the wrong value of e! :-)

Lint now checks for redefining mathematical constant.
