I fail this test because our implementation gives the result as

2.718281828459045e0

Looking at the representation of the values using
System.BitConverter.DoubleToInt64Bits (.NET) or
java.lang.Double.doubleToRawLongBits (Java) I get:

Expected result = 4613303445314885482

Actual result = 4613303445314885481

The bit pattern for System.Math.E (.NET) or java.lang.Math.E (Java) is
4613303445314885481.
