| 25 | 1 | equemene | <B>HPL_lmul</B> |
| 26 | 1 | equemene | multiplies without carry two long positive integers K and J |
| 27 | 1 | equemene | and put the result into I. The long integers I, J, K are encoded on |
| 28 | 1 | equemene | 31 bits using an array of 2 integers. The 16-lower bits are stored in |
| 29 | 1 | equemene | the first entry of each array, the 15-higher bits in the second entry |
| 30 | 1 | equemene | of each array. For efficiency purposes, the intrisic modulo function |
| 31 | 1 | equemene | is inlined. |

|
| 39 | 1 | equemene | <PRE>
|
| 40 | 1 | equemene | J (local input) int * |
| 41 | 1 | equemene | On entry, J is an integer array of dimension 2 containing the |
| 42 | 1 | equemene | encoded long integer J. |
