:::: When talking about floating point numbers to a REXXer (er, I think that's what I am ...), floating point is exact. 10.77 is precise (no approximations) and that's the way REXX stores it: the way you see it here. What you see is what you get. I realized that for most programmers, this isn't the case when it comes to the storage or expressing of floating-point numbers. I'd hate to have REXX excluded from this party because it uses an exact (base ten) floating point number repesentation with an (more-or-less) unbounded/unlimited mantissa (base ten), no guard digit(s), no binary representation of numbers. REXX knows nothing of IEEE-anything floating point. -- [[User:Gerard Schildberger|Gerard Schildberger]] 21:25, 13 August 2012 (UTC)
 
::::: No. REXX floating point is exact for fixed length binary fractions. However, you cannot represent the result of dividing 1 by 3 exactly. For example. Well, you can, but not using base that numeric representation. --[[User:Rdm|Rdm]] 21:35, 13 August 2012 (UTC)
