    Undergrad Finding quadratic irrationals from their decimal form

    My question is, for zeroes that can be represented in the form \dfrac{a + b\sqrt{c}}{d}, what is a good way to convert them from decimal form to that? I already know how to do it with continued fractions, but sometimes it requires too many digits of precision. so I'm probably looking for a...

    Undergrad Finding quadratic irrationals from their decimal form

    I already know it's possible to find what the quadratic irrational is with continued fractions. I made a thread about it on another forum. http://bbs.zoklet.net/showthread.php?t=11555

    Undergrad Finding quadratic irrationals from their decimal form

    Okay, this is something that's been bugging me for a while. A lot of the polynomials with higher powers can't be solved using algebraic methods and must be estimated. So my idea was to take these answers and find a way to convert them into an exact form, such as quadratic irrationals/surds...
