| 16 | 1 | equemene | .SH DESCRIPTION |
| 17 | 1 | equemene | \fB\&HPL_lmul\fR |
| 18 | 1 | equemene | multiplies without carry two long positive integers K and J |
| 19 | 1 | equemene | and put the result into I. The long integers I, J, K are encoded on |
| 20 | 1 | equemene | 31 bits using an array of 2 integers. The 16-lower bits are stored in |
| 21 | 1 | equemene | the first entry of each array, the 15-higher bits in the second entry |
| 22 | 1 | equemene | of each array. For efficiency purposes, the intrisic modulo function |
| 23 | 1 | equemene | is inlined. |
| 24 | 1 | equemene | .SH ARGUMENTS |
| 25 | 1 | equemene | .TP 8 |
| 26 | 1 | equemene | K (local input) int * |
| 27 | 1 | equemene | On entry, K is an integer array of dimension 2 containing the |
| 28 | 1 | equemene | encoded long integer K. |
| 29 | 1 | equemene | .TP 8 |
| 30 | 1 | equemene | J (local input) int * |
| 31 | 1 | equemene | On entry, J is an integer array of dimension 2 containing the |
| 32 | 1 | equemene | encoded long integer J. |
| 33 | 1 | equemene | .TP 8 |
| 34 | 1 | equemene | I (local output) int * |
| 35 | 1 | equemene | On entry, I is an integer array of dimension 2. On exit, this |
| 36 | 1 | equemene | array contains the encoded long integer result. |
