Round#
Versioned name: Round-5
Category: Arithmetic unary
Short description: Round performs element-wise round operation with given tensor.
Detailed description: Operation takes one input tensor and rounds the values, element-wise, meaning it finds the nearest integer for each value. In case of halves, the rule is to round them to the nearest even integer if mode
attribute is half_to_even
or rounding in such a way that the result heads away from zero if mode
attribute is half_away_from_zero
.
Input = [-4.5, -1.9, -1.5, 0.5, 0.9, 1.5, 2.3, 2.5]
round(Input, mode = `half_to_even`) = [-4.0, -2.0, -2.0, 0.0, 1.0, 2.0, 2.0, 2.0]
round(Input, mode = `half_away_from_zero`) = [-5.0, -2.0, -2.0, 1.0, 1.0, 2.0, 2.0, 3.0]
Attributes:
mode
Description: If set to
half_to_even
then the rule is to round halves to the nearest even integer, if set tohalf_away_from_zero
then rounding in such a way that the result heads away from zero.Range of values:
half_to_even
orhalf_away_from_zero
Type: string
Default value:
half_to_even
Required: no
Inputs
1: A tensor of type T. Required.
