I could only get pi accurate to 125 decimal places and root2 to 87, so cut the input strings accordingly.<br>
In fact the 1 digit error on desktop/Phix (below) don't happen in a browser
Increasing the precision helps but only up to a (relatively small) point, ie that 134 ''is'' needed, nowt greater helps at all. <br>
You may or may not have better luck with completely rewriting this to use mpq (rationals).
