# round

**round**(x[, n])

Return the floating point value x rounded to n digits after the
decimal point. If n is omitted, it defaults to zero. The result is a
floating point number. Values are rounded to the closest multiple of
10 to the power minus n; if two multiples are equally close, rounding
is done away from 0 (so. for example, `round(0.5)`

is `1.0`

and
`round(-0.5)`

is `-1.0`

).
