Subject [jira] [Commented] (MATH-1406) official support for compiling on GWT 2.8
Date Mon, 06 Mar 2017 10:20:33 GMT

    [ https://issues.apache.org/jira/browse/MATH-1406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15897037#comment-15897037
] 

Michael Borcherds commented on MATH-1406:
-----------------------------------------

I've run the official tests on FastMath on GWT + Core i7 in Chrome so my patch deletes almost
all of FastMath and uses Math instead

A lot slower:
abs 20
acos 14
atan2 21
cbrt 11
pow 12
asin 2.4
log 10
log10 12
log1p 13
hypot 20
expm1 2.0

No significant difference:
atan 1.2
cos 1.5
cosh 0.95
sin 1.4
sinh 0.84
tan 1.5
tanh 1.0

faster:
exp 0.64
sqrt 0.76

> With GWT 2.8.0 the changes needed aren't too hard to get most of it to compile
