*
|
|
* ARGUMENT
|
|
* unsigned a[];
|
|
* int p; power of 10 to divide by
|
|
* int n; number of digits
|

|
|
* DESCRIPTION
|
|
* Divides a number of n words (a) by a power of 10, c= a/10^p,
|
|
* a>=0, p>0, truncating the result, c is correct only if a/10^p<2^79.
|
|
*
|
|
* SIDE EFFECTS
|
|
* The value of a is destroyed.
