Re: Float serialization adds digits?

[Igmar Palsenberg]

I opened a Scala worksheet and put that in:

    import play.api.libs.json

    val v: Float = 12.345f
    json.JsNumber(v)

The result is

    v: Float = 12.345
    res3: play.api.libs.json.JsNumber = 12.345000267028809

Where do the additional digits come from? They are very annoying and I would like to just see 12.345.
I am using Play 2.5.14, has it been fixed since maybe?

You can't represent 12.345 in a float number. Floats have binary representation, not decimal. The real value of 12.345 is actually 12.34500026702880859375
