*
|
|
* This program reads the contents of the binary WDSP file "calculus"
|
|
* and dumps the data as two arrays of floating-point numbers
|
|
*
|
|
* The output is intended to be part of the file "calculus.c" which
|
|
* initializes these arrays (static data) for use with "memcpy"
|
|
* in emnr.c.
|
|
*
|
|
* Should the WDSP file "calculus" be changed, "calculus.c" should
|
|
* be re-generated using this program.
|
|
*
|
|
* return values of main()
|
|
*
|
|
* 0 all OK
|
|
* -1 sizeof(float) is not 8
|
|
* -2 error opening file "calculus"
|
|
* -3 read error
