[math] Rounding of negative zero

2014-01-12 Thread Thomas Neidhart

Hi, in MATH-1070 we have discovered that calling Precision.round(x, y) behaves differently for float and double values when the value to be rounded is negative zero: Precision.round(-0.0d, 0) = 0.0 Precision.round(-0.0f, 0) = -0.0 The reason being that in the double case, the value is converted
