Talk:Bound for Difference of Irrational Number with Convergent

''There is an old and no longer relevant discussion about this theorem at Talk:Value of Simple Continued Fraction. --barto (talk) (contribs) 12:45, 20 January 2018 (EST)''

It is important to let $x$ be any irrational number, and not only the limit of a SICF. Otherwise the argument in Irrational Number is Limit of Unique Simple Infinite Continued Fraction breaks. --barto (talk) 16:25, 17 July 2017 (EDT)
