Mathematica calculations can generate large precision number. One exemple is FFT and Inverse FFT. Nevertheless, when the calculaton is finished, you end up with very large precision number that are unnecessary, for exemple if you want to view the data in a data viewer package. More than that , the lare size of the generated files can impact the overall performance of the post processing (done outside mathematica) of your calculated output. Along this line,does someone have a suggestion to resolve the following issue: How do we store a mathematica output in a file (typically an array of real number) with a controlled precision ( whuch will be smaller than the mathematica precision for the initial mathematica output) Thanks Jeff
