Line 22:
:I recommend allowing a second optional parameter to indicate number of repeating digits. dec2frac(0.1234,2) would mean 0.123434343434... (written as 0.1234 with a bar over the "34), and should convert to 611/4950, while dec2frac(0.1234) or dec2frac(0.1234, 0) would mean *exactly* 0.1234 (1234/10000), which should convert to 617/5000. --[[User:Util|Util]] 13:48, 12 June 2011 (UTC)
