URL OF THE PROBLEM DOCUMENTATION :
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Math.html#floor(double)
A DESCRIPTION OF THE PROBLEM :
In the description section of the JavaDoc for Math.floor(), it says:
"Returns the largest (closest to positive infinity) double value that is not greater than the argument and is equal to a mathematical integer."
but then in the returns section, it says:
"the smallest (closest to negative infinity) floatingpoint value that is not less than the argument and is equal to a mathematical integer."
The latter is correct (assuming the docs for Math.ceil() are correct).
Release Regression From : 1.4.2
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.

The first line of Math.ceil and the returns line both describe Math.floor
The first line of Math.floor is correct (same as incorrect Math.ceil), but the returns line describes Math.ceil.
