int.rationalize([eps]) â rational Instance Public methods Returns the value as a rational. The optional argument eps is always ignored.

int.round([ndigits]) â integer or float Instance Public methods Rounds flt to a given precision in decimal digits (default 0 digits). Precision may be negative. Returns a floating point number when ndigits is positive, self for zero, and round down for negative. 1.round #=> 1 1.round(2) #=> 1.0 15.round(-1) #=> 20

int.succ â integer Instance Public methods Returns the Integer equal to int + 1. 1.next #=> 2 (-1).next #=> 0

int.times {|i| block } â selfint.times â an_enumerator Instance Public methods Iterates block int times, passing in values from zero to int - 1. If no block is given, an enumerator is returned instead. 5.times do |i| print i, " " end produces: 0 1 2 3 4 each
