Overview

Shortcut to define DecNums, e.g. 1._234567890123456789 produces Flt::DecNum(‘1.234567890123456789’) Based on coderrr.wordpress.com/2009/12/22/get-arbitrarily-precise-bigdecimals-in-ruby-for-just-one-extra-character/ There’s a problem with negative numbers with a null integer part: -0._1 is parsed as (-0)._1 and -0 is 0. The problem cannot be solved by redefinition of -@ for integers because -0 is interpreted as 0 by the Ruby parser (no runtime method call is involved). Such numbers have to be entered as -(0._1)
