BUILT-IN MATHEMATICA SYMBOL
Round
Round[x]
gives the integer closest to x.
Round[x, a]
rounds to the nearest multiple of a.
- Mathematical function, suitable for both symbolic and numerical manipulation.
- Round rounds numbers of the form x.5 toward the nearest even integer.
- Round[x] returns an integer when x is any numeric quantity, whether or not it is an explicit number.
- For exact numeric quantities, Round internally uses numerical approximations to establish its result. This process can be affected by the setting of the global variable $MaxExtraPrecision.
- Round applies separately to real and imaginary parts of complex numbers.
- Round automatically threads over lists.
