/* Again: Real vs. Imaginary */
::::For currency, you use a subset of the rational numbers, i.e., finite decimal fractions (even less, generally: <math>\mathbb{Z} / 100</math>. To speak of <math>\pi</math> dollars (or even $<math>\sqrt{2}</math>) is as surreal as to speak of ''3 + 2i'' dollars. ''Real numbers'' which aren't rational, are just a figment of our imagination, invented to ''help our calculations'', too--[[User:DiEb|DiEb]] 17:25, 17 August 2008 (EDT)
:::::I realized that and that's why I gave a second example, that of the length of a segment. Do you people really consider real numbers and imaginary numbers equal from the point of view of normal people? Let's not forget who is the target of this project.

::::::Presumably the purpose of articles like this is to provide accurate information, not to confirm misconceptions caused by terminology. Plenty of people use complex numbers regularly, and just because many people don't isn't a reason to have an inaccuracy in the article.--[[User_talk:Recorder|Recorder]] 17:42, 17 August 2008 (EDT)
