Determines conditional relationships between expressions.
val1 op val2
val1 |
- |
A scalar, series, or table. |
val2 |
- |
A scalar, series, or table. |
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 |
> |
Real |
yields Real |
Integer |

Series |
yields Series |

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.
The returned series of ones and zeros is called a "Binary Series".
