Groovy adds round() and truncate() methods to the Double and Float classes.
def doubleValue = 12.5456d assert 12.546d == doubleValue.round(3) assert 13 == doubleValue.round() assert 12 == doubleValue.trunc() assert 12.54d == doubleValue.trunc(2) def floatValue = 987.654f assert 987.65f == floatValue.round(2) assert 988 == floatValue.round() assert 987.6f == floatValue.trunc(1) assert 987 == floatValue.trunc()
