The FixPt Relational Operator block is a masked S-function that performs a comparison of its two inputs. The first input is converted the data type of the second input prior to comparison.The operator connecting the two inputs is selected with the Operator parameter list. The supported relational operators are given below.

Relational Operator	Description
==	TRUE if the first input is equal to the second input
!=	TRUE if the first input is not equal to the second input
<	TRUE if the first input is less than the second input
<=	TRUE if the first input is less than or equal to the second input
>=	TRUE if the first input is greater than or equal to the second input
>	TRUE if the first input is greater than the second input

The output is specified with the Logical output data type parameter. The output equals 1 for TRUE and 0 for FALSE. Note:
The Logical output data type selected should represent zero exactly. Data types that satisfy this condition include signed and unsigned integers and any floating-point data type.

The block icon displays the logic to be performed on the inputs. For a description of how the block icon displays the output data type, refer to "Block Icon Display".

Parameters and Dialog Box

Operator

Relational operator used to compare the two inputs.

Logical output data type

Output data type. You should only use data types that can represent zero exactly.

Conversions

The input with the smallest positive range is converted to the data type of the other input offline using round-to-nearest and saturation. This conversion is performed prior to comparison. Refer to "Parameter Conversions" in the manual for more information about parameter conversions.
