Gilles commented on MATH-1422: ------------------------------ It was certainly the other main goal. See the Javadoc of the {{FastMath}} class which mentioning a best effort to reach a 0.5 ulp precision, and the unit tests that validate the claim. I've suggested a rename to {{AccurateMath}}, since the only benchmarks we have do not seem to support the "Fast" qualifier... However I indeed do not know for sure whether there is still an advantage to using {{FastMath}}: see also * MATH-1114 > How accurate is FastMath javadoc? > --------------------------------- > > Key: MATH-1422 > URL: https://issues.apache.org/jira/browse/MATH-1422 > Project: Commons Math > Issue Type: Bug > Reporter: Roman Leventov > > Javadoc to FastMath states that it is a "faster, more accurate alternative to > java.lang.Math" since at least 2012: > https://github.com/apache/commons-math/blob/696be68b5dc8872a818a24d8a377158314b54e31/src/main/java/org/apache/commons/math3/util/FastMath.java > How accurate is this assertion in 2017, Java 8? -- This message was sent by Atlassian JIRA (v6.4.14#64029)
