:Presumably we are only working to the precision (or double precision) of the system registers, (or to the number of digits originally provided in numerical string based implementations), so the values would all be rational. --[[User:Markhobley|Markhobley]] 12:28, 12 June 2011 (UTC)
:: System registers? Double precision? I ain't knowing nuttin' 'bout registers or doubles nohow, noway. The REXX language (for instance) doesn't use floating point, nor registers. It uses whatever precision is in effect, and that may be increased to almost anything pratical (eight million digits is about the useful limit). -- [[User:Gerard Schildberger|Gerard Schildberger]] 19:23, 13 August 2012 (UTC)
:Definitions: Rationals - the real numbers constructible as ratio of A/B, where A and B are both integers. Irrationals - the real numbers that cannot be expressed as such a ratio.
