separation |between |integer |and |fractional |parts
real |- | |correct |answers |a |data |type |representing |numbers |that |can |have |fractional |parts, |often |
called |floating-point |numbers
reclocking |- | |correct |answers |the |process |of |refreshing |the |timing |signals |in |digital |data |to |
ensure |accuracy |and |synchronization
