They start off that way
data = {1.0, 1000.0, Pi // N};
Precision /@ data
{MachinePrecision,MachinePrecision,MachinePrecision}
Precision /@ Gamma[data]
{MachinePrecision,12.1834,MachinePrecision}

Hi guys
When I write numbers in my code, I do it as (e.g.)
1.0
1000.0
Pi //N
etc...
Is it correct to say that my calculations are done with machine-
precision, i.e. with rougly 16 digit precision?
Regards,
Jim.
