epsilon:=1E-12:; exact(0.324532453245); float2rational(0.324532453245) ↵ returns
"Done", 1094980201/3374023738, 295/909

But if you use epsilon:=5E-12, as suggested by Joe to get the same results as Home's fraction button, exact() provides the same result as float2rational(). The magnitude of epsilon controls how far the reduction is continued.
