It appears that in Java, the expression

Math.exp(1.0e0) == Math.E

returns false ;-(

I'm not sure exactly what the IEEE spec has to say about the required precision
of the result: it needs a lot of study to decipher the meaning. Pragmatically,
it would appear to make sense for our expected result to tolerate the value
that the Java library delivers, as well as what would appear to be the
"correct" result. So I propose to change the test to allow an epsilon variation
in the result.
