method
subsec
ruby latest stable - Class:
Time
subsec()public
Returns the fraction for time.
The return value can be a rational number.
t = Time .now #=> 2009年03月26日 22:33:12 +0900 "%10.9f" % t.to_f #=> "1238074392.940563917" t.subsec #=> (94056401/100000000)
The lowest digits of #to_f and #subsec are different because IEEE 754 double is not accurate enough to represent the rational number.
The more accurate value is returned by #subsec.
