Hi, 0.01 is MachinePrecision. If you bloat the accuracy of some numbe, random (binary) digits are added, that is the content of the corresponding memory. hope this helps, Daniel Aaron Fude wrote: > The following two commands result in different values: > > SetPrecision[0.01, 50] > 0.01`50 > > Is that because in the first case, 0.01 is first represented as a > double and then passed to SetPrecision, while in the second case, > Mathematica gets a chance to interprete 0.01 as 1/100? > > Thanks! > > Aaron > -- Daniel Huber Metrohm Ltd.
