Determines whether x falls within a range specified by the upper limit and lower limit inputs and optionally coerces the value to fall within the range. The function performs the coercion only in Compare Elements mode. This function accepts time stamp values if all inputs are time stamp values. You can change the comparison mode of this function.
The connector pane displays the default data types for this polymorphic function.

This function compares each data type according to the Boolean comparison rules. If the function is in Compare Aggregates mode, it returns the unchanged value of x in coerced(x) rather than a coerced value. If x is greater than upper limit and the function is in Compare Elements mode (default), the function coerces x to the upper limit value. If x is less than lower limit and the function is in Compare Elements mode, the function coerces x to the lower limit value.
In the case of numeric values, the upper limit, lower limit, and x inputs do not have to be the same data type representation.
By default, In Range And Coerce includes the lower limit value in the range, as indicated by the solid black diamond at the lower limit input. By default, the upper limit value is not included in the range, as indicated by the empty diamond at the upper limit input.
To change whether the function includes the value wired to upper limit or lower limit, right-click the function and select Include upper limit or Include lower limit from the shortcut menu to include or remove the value in the range. These options only affect the result of In Range?. The function always coerces x to the exact values of upper limit or lower limit, regardless of whether you select Include upper limit or Include lower limit from the shortcut menu.
If the lower limit value is greater than the upper limit value, LabVIEW switches the values internally without displaying an error message. If the function is in Compare Elements mode, it still coerces x to either the upper limit or lower limit value. However, In Range? is always FALSE, even if x is between the lower and upper limits.
