Description
Implements a 32-bit (2^31-2 cycle length) linear congruential random number generator.
- Range: 1 ... 2^31-2
- Period length: 2^31-2
- Method: x=(x * 7^5) mod (2^31-1)
- Required hardware: exactly 32-bit integer arithmetics
- To check: if x[0]=1 then x[10000]=1,043,618,065

Member Function Documentation
◆ str()
|
overridevirtual |
Returns a brief, one-line description of the object. The returned string does (should) NOT include the object's name and class. This method is used to display object information at several places in the Qtenv GUI, among others.
Reimplemented from cObject.
◆ initialize()
|
overridevirtual |
Sets up the RNG.
Implements cRNG.
◆ selfTest()
|
overridevirtual |
Tests correctness of the RNG
Implements cRNG.
◆ intRand() [1/2]
|
overridevirtual |
Random integer in the range [0,intRandMax()]
Implements cRNG.
◆ intRandMax()
|
overridevirtual |
◆ intRand() [2/2]
|
overridevirtual |
Random integer in [0,n), n < intRandMax()
Implements cRNG.
◆ doubleRand()
|
overridevirtual |
Random double on the [0,1) interval
Implements cRNG.
◆ doubleRandNonz()
|
overridevirtual |
Random double on the (0,1) interval
Implements cRNG.
◆ doubleRandIncl1()
|
overridevirtual |
Random double on the [0,1] interval
Implements cRNG.
