## NAME

__gnu_cxx::subtractive_rng## SYNOPSIS

Inherits std::unary_function< _Arg, _Result >. Public Types typedef _Arg argument_type argument_type is the type of the argument typedef _Result result_type result_type is the return type Public Member Functions subtractive_rng (unsigned int __seed) Ctor allowing you to initialize the seed. subtractive_rng () Default ctor; initializes its state with some number you don't see. void _M_initialize (unsigned int __seed) unsigned int operator() (unsigned int __limit) Returns a number less than the argument. Detailed Description The subtractive_rng class is documented on SGI's site. Note that this code assumes that int is 32 bits. Definition at line 352 of file ext/functional.
