FastMath is not an exact replacement for StrictMath
---------------------------------------------------

                 Key: MATH-478
                 URL: https://issues.apache.org/jira/browse/MATH-478
             Project: Commons Math
          Issue Type: Improvement
            Reporter: Sebb


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.
