Declares a random variable of type RndUniI. With each access, such a variable contains a value that is generated following a uniform distribution with intervals. With a random variable of type RndUniI you can define multiple intervals of random integer values.
RndUniI( l1..u1=p1, ..., ln..un=pn ): number;
number
Parameter | Description |
---|---|
l_{1} | Lower boundary of the first interval of random values (number) |
u_{1} | Upper boundary of the first interval of random values (number) |
p_{1} | Probability of choosing the first interval of values (float) |
ln | Lower boundary of the nth interval of random values (number) |
un | Upper boundary of the nth interval of random values (number) |
pn |
Probability of choosing the nth interval of values (float) Condition: pi = 1; i : li <= ui |
dclrand rEvent1, rEvent2 : RndBin(0.25); rTime1 : RndExpF(5.5); rTime2 : RndUniF(0.5..12.5); rCube : RndUniN(1..6); rPrice : RndUniN(10..2000); rArtNo : RndUniI(1..50=0.6, 51..100=0.3, 101..10000=0.1); dclsql UpdArticle: UPDATE article SET price = :rPrice WHERE articlenumber = :rArtNo;
The random variable rArtNo is used in a SQL command to access an article with a random article number. 60% of all integer random values are between 1 and 50, 30% are between 51 and 100 and 10% are between 101 and 10000.
