Detailed Description

Boolean value, which can be either true or false.

OTX Boolean values have a value space of true, false, 1, 0. Even though 1 and 0 are contained in the value space, treating Boolean values like numeric values directly is not allowed by OTX. Boolean is the result data type of comparison and equality operations. A bool expression can be a controlling conditional expression in Branch, Loops etc.

Note

If a Boolean declaration is not explicitly initialized, false is assigned to the declaration.

Conversion Terms

Conversion	Result	Sample
ToBoolean	Returns the copy of the value	Boolean b = ToBoolean(true); // Returns true
ToInteger	Returns 1 if the value is true, otherwise 0	Integer i = ToInteger(true); // Returns 1
ToFloat	Returns 1.0 if the value is true, otherwise 0.0	Float f = ToFloat(true); // Returns 1.0
ToString	Returns "true" if the value is true, otherwise "false"	String s = ToString(true); // Returns "true"
ToByteField	Returns 0x01 if the value is true, otherwise 0x00	ByteField bf = ToByteField(true); // Returns 0x01
