Limit

(Engine-Level Function)

Description	Set Value Minimum and Maximum. This function returns a value that is limited both on the high and low ranges.
Returns	Numeric
Usage	Script or steady state.
Function Groups	Rounding Math
Related to:	Max | Min
Format:	Limit(X, Low, High)
Parameters

X

Required. The variable whose numeric value will be limited.

Low

Required. Any numeric expression giving the lower limit for the value X.

High

Required. Any numeric expression giving the upper limit for the value X.

Comments

This function performs the same operation as Min(High, Max(Low, X)) but is simpler to write and requires less memory. If the value exceeds one of the limits, the function returns that limit. Otherwise, the value is returned unchanged. If Low is greater than High, the value for High is returned. If any of the parameters is invalid, the function returns invalid.

Examples:

a = Limit(123.4, 0, 100);
b = Limit(-2.6, 0, 100);
c = Limit(36.7, 0, 100);
d = Limit(36.7, Invalid, 100);

The values for a, b, c, and d are 100, 0, 36.7 and invalid, respectively.
