# Round

Round[x]
gives the integer closest to x.

Round[x,a]
rounds to the nearest multiple of a.

## DetailsDetails

• 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.
