in reply to Determining if a rational number terminates


What you really mean is "does this rational number's decimal expansion have a form that ends with zeros?". 1/10 has two forms: 0.1000000000... and 0.099999999999... They are equal.

    They are equal, but one is generally recognised as the more canonical representation.

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
