Regression test failure - RC 99 (poisson mean comparison fails)

[caffreyj]

Random comparison of interval_nn,xml files when calculating the Poisson mean (Expected text value '0.02097365841662402' but was '0.02097365841662424'). Note the difference in value is clearly insignificant - should be rounding the value before making the comparison

Fix looks to be to reduce the level of precision when calculating the the Poisson mean from double to normal precision
