std::ranlux48

typedef discard_block_engine <ranlux48_base, 389, 11> ranlux48;

Ranlux 48 generator

A subtract-with-carry pseudo-random generator of 48-bit numbers with accelerated advancement.

It is an instantiation of the discard_block_engine adaptor on a subtract_with_carry_engine with the following template parameters:

parameter	name	value
`Engine`	base engine	`ranlux48_base`
`p`	block size	`389`
`r`	used block	`11`

Member types

The following alias is a member type of ranlux48:

member type	definition	notes
`result_type`	`uint_fast64_t`	The type of the numbers generated.

As a discard_block_engine type, it has the following member functions:

(constructor): Construct discard-block engine (public member function)

min: Minimum value (public static member function)

max: Maximum value (public static member function)

seed: Seed base engine (public member function)

operator(): Generate random number (public member function)

discard: Advance internal state (public member function)

Non-member functions
