Struct `std.random.LinearCongruentialEngine`

Linear Congruential generator.



struct LinearCongruentialEngine(UIntType, UIntType a, UIntType c, UIntType m)


  


if (isUnsigned!UIntType);

Constructors

Name	Description
`this`	Constructs a LinearCongruentialEngine generator seeded with `x0`.

Properties

Name	Type	Description
`front`[get]	`UIntType`	Returns the current number in the random sequence.
`save`[get]	`typeof(this)`

Methods

Name	Description
`opEquals`	Compares against rhs for equality.
`popFront`	Advances the random sequence.
`seed`	(Re)seeds the generator.

Example

Declare your own linear congruential engine

alias CPP11LCG = LinearCongruentialEngine!(uint, 48271, 0, 2_147_483_647);

// seed with a constant
auto rnd = CPP11LCG(42);
auto n = rnd.front; // same for each run
writeln(n); // 2027382

Example

Declare your own linear congruential engine

// glibc's LCG
alias GLibcLCG = LinearCongruentialEngine!(uint, 1103515245, 12345, 2_147_483_648);

// Seed with an unpredictable value
auto rnd = GLibcLCG(unpredictableSeed);
auto n = rnd.front; // different across runs
