RND
RND(integer-expression, integer-expression)Returns a pseudo-random number between the two integer expressions (inclusive). The pseudo-random number generator uses a Mersenne Twister mt19937 algorithm to produce random results, with entropy seeded from the operating system kernel via various inputs which are not directly under user control.
NOTE: This differs from BBC BASIC which used a simple 33-bit LFSR (Linear Feedback Shift Register) as opposed to Mersenne Twister.
This function should not be relied upon for cryptographic randomness as its seed value cannot be guaranteed secure.
