Re: Is There a Way to Rationalize a Decimal in Pari/GP?

Thanks Bill (and John who contacted me off list). -- bestappr() does the trick!

In my case I always want the exact fraction, so I have to make sure I
specify a large enough denominator. I am converting long decimals, and
I don't want to count decimal places. The easy solution seems to be to
pass bestappr() an arbitrarily large power of 10, like
bestappr(0.1000000000000000055511151231257827021181583404541015626,10^100).
