Last Modified: January 12, 2018

Determines whether the input value falls within a range specified by the upper and lower limits and optionally coerces the value to fall within the range.

To allow the node to perform coercion, select Elements in the Behavior section of the Item tab.

upper limit

The upper limit of the range.

By default, this node excludes the value of upper limit in the range. You can configure the node to include the value of upper limit in the range by selecting the Include upper limit option in the Behavior section of the Item tab. This option affects only the value of in range?. This node always coerces x to the exact values of upper limit and lower limit, regardless of whether you select this option.

Data Type Changes on FPGA

When you add this node to a document targeted to an FPGA, this input has a default data type that uses fewer hardware resources at compile time.

x

The value to test in the range and optionally coerce if it does not fall between the upper and lower limits. This input changes to waveform when the data type is a waveform.

This input supports all data types.

lower limit

The lower limit of the range.

By default, this node includes the value of lower limit in the range. You can configure the node to exclude the value of lower limit in the range by deselecting the Include lower limit option in the Behavior section of the Item tab. This option affects only the value of in range?. This node always coerces x to the exact values of upper limit and lower limit, regardless of whether you select this option.

in range?

A Boolean value that indicates whether the input value is in range.

True x is in range.
False x is out of range. This node also returns False if x, upper limit, or lower limit is NaN.

In Compare Elements mode, the data type structure of in range? matches the data type structure of x, with each scalar replaced by a Boolean value.

datatype_icon

coerced

The coerced or unchanged input value.

Comparison Modes and x Value Behavior

If x is within the range set by the upper limit and lower limit or if the node is in Compare Aggregates mode, the value is unchanged. If x is not in range and the node is in Compare Elements mode, the node converts the value to the same value as upper limit or lower limit. If upper limit, x, or lower limit is NaN, coerced is NaN.

Where This Node Can Run:

Desktop OS: Windows

FPGA: DAQExpress does not support FPGA devices

Web Server: Supported in VIs that run in a web application
