angle units

Units of the input and output angles.

Name Value Description
radian in, radian out 0 The units of input and output angles are both radian.
radian in, degree out 1 The unit of input angles is radian. The unit of output angles is degree.
degree in, degree out 2 The units of input and output angles are both degree.
degree in, radian out 3 The unit of input angles is degree. The unit of output angles is radian.

Default: radian in, radian out

datatype_icon

angle

Angle that this node rotates.

This input accepts the following data types:

  • Double-precision, floating-point number
  • 1D array of double-precision, floating-point numbers
datatype_icon

counterclockwise rotation

Amount that this node uses to rotate the angle in the counterclockwise direction. counterclockwise rotation must have the same unit as angle.

This input accepts the following data types:

  • Double-precision, floating-point number
  • 1D array of double-precision, floating-point numbers

How the Data Type of counterclockwise rotation Affects Node Behavior

If this input is a double-precision, floating-point number, you can wire a double-precision, floating-point number or a 1D array of double-precision, floating-point numbers to angle. This node uses the amount to rotate one angle or multiple angles in the counterclockwise direction.

If this input is a 1D array of double-precision, floating-point numbers, you must wire a 1D array of double-precision, floating-point numbers to angle. The number of elements in counterclockwise rotation must equal the number of elements in angle. Otherwise, this node returns an error.

datatype_icon

rotated angle range

Range of values for the rotated angle.

Name Value Description
none 0 The range is [-Inf , Inf].
-180 to 180 (-pi to pi) 1 The range is [-180, 180] in degrees or [-pi, pi] in radians.
0 to 360 (0 to 2pi) 2 The range is [0, 360] in degrees or [0, 2pi] in radians.

Default: -180 to 180 (-pi to pi)

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

rotated angle

Output angle after the rotation.

This output can return the following data types:

  • Double-precision, floating-point number
  • 1D array of double-precision, floating-point numbers

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
