Description
The specification for java.lang.Math talks about the accuracy of the methods there in terms of ulps (units in the last place).  Ulps are a common way of describing relative error in floating-point functions.  However, none of the Math, StrictMath, Float, and Double classes include methods in calculate the ulp of a floating-point value.
