[R] double.xmin really the smallest non-zero normalized floating-point number?

2013-09-10 Thread Marius Hofert
Hi, ?.Machine says that 'double.xmin' is 'the smallest non-zero normalized floating-point number'. On my machine, this is 2.225074e-308. However, 2.225074e-308 / 2 is 0 and smaller than 2.225074e-308, so double.xmin is not the smallest such number (?) Am I missing anything? Cheers, Marius
