Functions¶
mathRandomInteger¶
Integer mathRandomInteger ( in Size seed, in Size index )
Generate an element of a sequence of uniformly-distributed random Integers between 0 and 2^29-1 (inclusive)
注釈
Each sequence is periodic with period length of 536,870,912. However, sequence seed + 1 overlaps with sequence seed after 1,048,576 elements, so take care using different sequences.
| seed | The sequence number |
| index | The index within the sequence |
/*
** Example: mathRandomInteger
*/
require Math;
operator entry() {
// generate 10 random Integers from sequence 18
Integer values[10];
for (Index i = 0; i < 10; ++i)
values[i] = mathRandomInteger(18, i);
report(values);
}
