Other machines, for instance IBM C RS6000, calculate a T of about 1.0E-15 in this case, C due probably to filling up the multiplicands with 32 C bits of zeros in the registers. Therefore, it is a good idea to draw the A curve with C a blunt numerical pencil. However, the fudge factor C is very small, and should be of no consequence for C the practical cosmologist. However, tests show C that machine precision tends to be coarse enough so C that if one is analytically off the curve, one is far C enough away so as to encounter no problems later on.

All internal quantities are higher C precision to avoid conversions.
C Reporting is normally enabled, because the result is not C necessarily useful in this case, but the knowledgeable user might C wish to have this behaviour.
