java - Double convert to Fraction -


i want double convert value fraction (in java).

example: 0.33333 -> 1/3

i have many examples fraction found, not me. numbers between 0 1.

has perhaps have idea?

tahnks,

i guess want approximate fraction representation of double value (like example)

a simple way try denominators 1 one:

double doubleval = 0.33333; double negligibleratio = 0.01;  for(int i=1;;i++){     double tem = doubleval/(1d/i);     if(math.abs(tem-math.round(tem))<negligibleratio){         system.out.println(math.round(tem)+"/"+i);         break;     } }

this prints 1/3. if set double doubleval = 0.6363636;, prints 7/11.

you can change negligibleratio bigger value if want more succinct fraction result.
