Author	SHA1	Message	Date
Roberto Ierusalimschy	6eb53b7526	Details Several details in code (e.g., moving a variable to the most inner scope that encloses its uses), comments, parameter names, extra tests.	5 years ago
Roberto Ierusalimschy	2d92102dee	'l_mathlim' renamed to 'l_floatatt' That macro is applied to float attributes, not to limits.	5 years ago
Roberto Ierusalimschy	b96b0b5abb	Added macro 'luaL_pushfail' The macro 'luaL_pushfail' documents all places in the standard libraries that return nil to signal some kind of failure. It is defined as 'lua_pushnil'. The manual also got a notation (@fail) to document those returns. The tests were changed to be agnostic regarding whether 'fail' is 'nil' or 'false'.	5 years ago
Roberto Ierusalimschy	2f22c6bb79	'math.randomseed' always returns the two seed components	5 years ago
Roberto Ierusalimschy	4eefef07ab	'math.randomseed()' returns the seeds it used A call to 'math.randomseed()' returns the two components of the seed it set, so that they can be used to set that same seed again.	5 years ago
Roberto Ierusalimschy	347d6961ac	Define LUA_MAXUNSIGNED as a preprocessor constant The previous definition of LUA_MAXUNSIGNED used a typecast, making it unsuitable for constant expressions in the preprocessor.	6 years ago
Roberto Ierusalimschy	279c3a6961	A few changes in tests about number of bits in integers - The preprocessor must work with at least 'long', and therefore must do shifts of up to 31 bits correctly. - Whenever possible, use unsigned types in shifts.	6 years ago
Roberto Ierusalimschy	9eca305e75	'math.randomseed()' sets a somewhat random seed When called with no arguments, 'math.randomseed' uses time and ASLR to generate a somewhat random seed. the initial seed when Lua starts is generated this way.	6 years ago
Roberto Ierusalimschy	51316f9df7	'math.rand()' uses higher bits to produce float value The call 'math.rand()' converts the higher bits of the internal unsigned integer random to a float, instead of its lower bits. That ensures that Lua compiled with different float precisions always generates equal (up to the available precision) random numbers when given the same seed.	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
Roberto Ierusalimschy	aedcfb9414	type 'Rand64' may not be long long, so it should not use 'LL' in its constants	6 years ago
Roberto Ierusalimschy	de53c2ec7e	using some weak "randomness" (time and memory address) to initialize seeds for the PRNG	7 years ago
Roberto Ierusalimschy	80bd4a8940	correction on xoshiro256** algorithm (should use state[1] instead of state[0] for output)	7 years ago

Roberto Ierusalimschy	b8a04658b2	PRNG changed from 'xoroshiro128+' to 'xoshiro256**' + "I' renamed 'Rand64' + implementation can use integer types larger than 64 (or 32) bits	7 years ago
Roberto Ierusalimschy	b44787652b	using 'xoroshiro128+' for PRNG (plus a rotate at the final result to have better lower bits)	7 years ago
Roberto Ierusalimschy	bdd10a08b1	in 'random', uses high-order bits instead of low-order (better statistical properties)	7 years ago
Roberto Ierusalimschy	c5e3b2f814	in random/'project', remove the special case for "small" intervals; it is slower than the general case.	7 years ago
Roberto Ierusalimschy	89da4168df	avoid functions named 'pack' (name too common, may collide when doing 'onelua.c')	7 years ago
Roberto Ierusalimschy	6b01b6cf6a	'lu_int32' may not be 'int'	7 years ago
Roberto Ierusalimschy	e3388ebfad	more explicit casts when converting an integer to a random float (to ensure computations are done with all bits)	7 years ago
Roberto Ierusalimschy	dbec41f34c	random floats of different sizes get exactly needed number of random bits (up to 64)	7 years ago
