U:RDoc::NormalClass[iI"Random:ET@I"	base;To:RDoc::Markup::Document:@parts[o;;[o:RDoc::Markup::Paragraph;[	I"ORandom provides an interface to Ruby's pseudo-random number generator, or ;TI"QPRNG.  The PRNG produces a deterministic sequence of bits which approximate ;TI"Ntrue randomness. The sequence may be represented by integers, floats, or ;TI"binary strings.;To:RDoc::Markup::BlankLine�o;	;[I"HThe generator may be initialized with either a system-generated or ;TI"4user-supplied seed value by using Random.srand.;T@o;	;[I"QThe class method Random.rand provides the base functionality of Kernel.rand ;TI"Ialong with better handling of floating point values. These are both ;TI"(interfaces to the Ruby system PRNG.;T@o;	;[	I"LRandom.new will create a new PRNG with a state independent of the Ruby ;TI"Msystem PRNG, allowing multiple generators with different seed values or ;TI"Gsequence positions to exist simultaneously. Random objects can be ;TI";marshaled, allowing sequences to be saved and resumed.;T@o;	;[I"RPRNGs are currently implemented as a modified Mersenne Twister with a period ;TI"Rof 2**19937-1.  As this algorithm is _not_ for cryptographical use, you must ;TI"Ause SecureRandom for security purpose, instead of this PRNG.;T@o;	;[I"QSee also Random::Formatter module that adds convenience methods to generate ;TI""various forms of random data.;T:
