Subject [jira] Commented: (MATH-478) FastMath is not an exact replacement for StrictMath
Date Fri, 21 Jan 2011 20:43:44 GMT

    [ https://issues.apache.org/jira/browse/MATH-478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12984923#action_12984923
] 

Luc Maisonobe commented on MATH-478:
------------------------------------

OK, I'll fix the nextAfter(float, double) signature and I'll take care of implementing the
missing functions.

I will also try to set up a proper implementation for hypot.

> FastMath Javadoc says:
> "Faster, more accurate, portable alternative to StrictMath."
> However, it does not implement the following StrictMath methods:
> hypot(double, double)
> IEEEremainder(double, double)
> Nor the following, though it probably should:
> signum(float)
> ulp(float)
> FastMath implements the following additional methods:
> acosh(double)
> asinh(double)
> atanh(double)
> nextAfter(double, double)
> nextUp(double)
> I think this should be documented.
