< <= > >= == != (Conditional Operators)

Purpose:

Determines conditional relationships between expressions.

Syntax:

val1 op val2

val1	-	A scalar, series, or table.
val2	-	A scalar, series, or table.

Returns:

A scalar, series, or table (containing the value 1 or 0) of the same type as the higher of the two expressions. 1: True; 0: False. Integer is the lowest type, Real is next, and Complex is the highest type. If one or both of the expressions is a series, then a series results. The following is a list of type conversion rules:

Integer	op	Real	yields Real
Integer	op	Series	yields Series
Integer	op	Integer	yields Integer
Real	op	Complex	yields Complex
Real	op	Series	yields Series
Complex	op	Real Series	yields Complex Series

The following relational operators and functions are supported:

Operator	Function	Description
<	LESSER	left value less than right value
<=	LESSEREQUAL	left value less than or equal to right value
>	GREATER	left value greater than right value
>=	GREATEREQIAL	left value greater or equal to right value
==	ISEQUAL	left value equal to right value
!=	NOTEQUAL	left value not equal to right value

Example:

max(W1) <= 10.0

returns a 1 if the maximum value of W1 is less than or equal to 10.0, or 0 if the maximum value of W1 is not less than or equal to 10.0. If W1 contains a series, then

W1 > 10.0

returns a series the same length as W1 containing a 1 for each observation that is greater than 10 and 0 for each observation that is less than or equal to 10.0.
