<H1>Description</H1> |
| 25 |
<B>HPL_lmul</B> |
| 26 |
multiplies without carry two long positive integers K and J |
| 27 |
and put the result into I. The long integers I, J, K are encoded on |
| 28 |
31 bits using an array of 2 integers. The 16-lower bits are stored in |
| 29 |
the first entry of each array, the 15-higher bits in the second entry |
| 30 |
of each array. For efficiency purposes, the intrisic modulo function |
| 31 |
is inlined. |

<H1>Arguments</H1> |
| 34 |
<PRE>
|
| 35 |
K (local input) int * |
| 36 |
On entry, K is an integer array of dimension 2 containing the |
| 37 |
encoded long integer K. |
| 38 |
</PRE>
|
| 39 |
<PRE>
|
| 40 |
J (local input) int * |
| 41 |
On entry, J is an integer array of dimension 2 containing the |
| 42 |
encoded long integer J. |
| 43 |
</PRE>
|
| 44 |
<PRE>
|
| 45 |
I (local output) int * |
| 46 |
On entry, I is an integer array of dimension 2. On exit, this |
| 47 |
array contains the encoded long integer result. |
