	A <value> greater or equal to 255 corresponds to a 100% probability that the first block is taken. With a <value> of -1, the "else" block is taken every time. (A <value> of 0 means taking the "if" block once out of 256 on average).		A <value> greater or equal to 255 corresponds to a 100% probability that the first block is taken. With a <value> of -1, the "else" block is taken every time. (A <value> of 0 means taking the "if" block once out of 256 on average).

			The math can be counter-intuitive, putting it simple:
			* ''ifrnd 0'' will return true 1/256 of cases;
			* ''ifrnd 127'' will return true 128/256 of cases;
			* ''ifrnd 255'' will return true 256/256 of cases;
