Subject [jira] [Commented] (NUMBERS-43) Remove "round(float)" methods?
Date Tue, 13 Jun 2017 19:53:01 GMT

    [ https://issues.apache.org/jira/browse/NUMBERS-43?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16048313#comment-16048313

Gilles commented on NUMBERS-43:
-------------------------------

bq. just saw the code and at some point its anyway calling method which return double

Hmm, I don't think so; the implementations for {{double}} and {{float}} are segregated. Otherwise
(IIUC), the semantics of rounding would not be preserved.  The point here is rather whether
anyone would be using {{float}}s for computations nowadays.

Finance is a domain where rounding must be controlled, but is a {{round}} method enough to
satisfy the constraints of that field?

> In class {{Precision}}, there are methods for rounding {{float}} values, e.g.
> {code:java}
> public static float round(float x, int scale, int roundingMethod) { /* ... */ }
> {code}
> Is there any use for supporting specific handling of floats (in these times where memory
is not a scarce resources anymore)?
