A numeric data file contains a list of integer or real numbers that can be accessed as a one dimensional array. Multiple numbers can be listed on each line. Comment and blank lines may also be included. You can optionally include a check sum to ensure the integrity of the data.

• Comments and blank lines are ignored and are not included in the check sum. Comment lines are denoted by a colon in the first column. You can also place a comment after numbers as well.


• Only printable characters (no tabs) are allowed in a Data file.


• End of line delimiters in the data file may be Return/Line Feed, Line Feed, Return, or Line Feed/Return.

Here is an example data file containing integer values:

In this example of a real number data file, hexadecimal format is used so that their binary representation is precise.

:
:  Reciprocals of primes from 3 to 127.  A fudge factor of .0000000000000005 is
:  added so that when multiplying them any rounding error is always positive.
