.SH DESCRIPTION |
17 |
\fB\&HPL_lmul\fR |
18 |
multiplies without carry two long positive integers K and J |
19 |
and put the result into I. The long integers I, J, K are encoded on |
20 |
31 bits using an array of 2 integers. The 16-lower bits are stored in |
21 |
the first entry of each array, the 15-higher bits in the second entry |
22 |
of each array. For efficiency purposes, the intrisic modulo function |
23 |
is inlined. |

.SH ARGUMENTS |
25 |
.TP 8 |
26 |
K (local input) int * |
27 |
On entry, K is an integer array of dimension 2 containing the |
28 |
encoded long integer K. |
29 |
.TP 8 |
30 |
J (local input) int * |
31 |
On entry, J is an integer array of dimension 2 containing the |
32 |
encoded long integer J. |
33 |
.TP 8 |
34 |
I (local output) int * |
35 |
On entry, I is an integer array of dimension 2. On exit, this |
36 |
array contains the encoded long integer result. |
