![]() ![]() This function uses the Mersenne Twister random number generator, MT19937, written by Takuji Nishimura and Makoto Matsumoto, Shawn Cokus, Matthe Bellew and Isaku Wada. Random, rand, 0.0, 1.0 Comments based on the original source Generates a random floating point number in the range 0.0 to 1.0 and stores it in rand. Known limitations for floating point: 1) only about 4,294,967,296 distinct numbers can be generated for any particular range, so all other numbers in the range will never be generated 2) occasionally a result can be slightly greater than the specified Max (this is caused in part by the imprecision inherent in floating point numbers). Otherwise, the result will be an integer. If either Min or Max contains a decimal point, the end result will be a floating point number in the format set by SetFormat. This command yields a pseudo-randomly generated number, which is a number that simulates a true random number but is really a number based on a complicated formula to make determination/guessing of the next number extremely difficult.Īll numbers within the specified range have approximately the same probability of being generated (however, see "known limitations" below). This value travels from 0 to 4294967295 every ~7.2 minutes. If reseeding is never done by the script, the seed starts off as the low-order 32-bits of the 64-bit value that is the number of 100-nanosecond intervals since January 1, 1601. Generally, reseeding does not need to be done more than once. Reseeding can improve the quality/security of generated random numbers, especially when NewSeed is a genuine random number rather than one of lesser quality such as a pseudo-random number. NewSeed should be an integer between 967295 (0xFFFFFFFF). This affects all subsequently generated random numbers. ![]() This mode reseeds the random number generator with NewSeed (which can be an expression). The largest allowed value is 2147483647 for integers, but floating point numbers have no restrictions. Otherwise, specify the largest number that can be generated, which can be negative, floating point, or an expression. If blank or omitted, it defaults to 2147483647. The lowest allowed value is -2147483648 for integers, but floating point numbers have no restrictions. Otherwise, specify the smallest number that can be generated, which can be negative, floating point, or an expression. Min If blank or omitted, it defaults to 0. The format of stored floating point numbers is determined by SetFormat if its slow mode is used otherwise SetFormat only affects formatting when the number is converted to a string.
