A lexical byte constant evaluates to a value of type byte.
The internal representation of bytes is 8-bit signed two's-complement.
Overflows or underflow's during byte computations do not throw exceptions.
Compare to byte concept and return difference between two byte concept.
print Byte.create(12).comapreTo( Byte.create(10) ) ---> 2
For convert the byte concept to Integer or Real concept use:
print Byte.create(12).getInteger.getConceptType ---> Integer
print Byte.create(20).getReal.getConceptType ---> Real

| Parameters: |
| $value : | the initial value of the Byte concept. |
|
Constructs a Byte concept initialized to the specified Integer concept.
| Parameters: |
| $value : | the String concept to be converted to a Byte concept. |
|
| Exceptions: |
unparsableNumberException :
(Error) | If the String does not contain a parsable byte. |
Constructs a Byte concept initialized to the value specified by the String parameter.
| Parameters: |
| $value : | the Byte concept to be compared. |
|
Compares two Byte concepts numerically.Returns :
- the value 0 if the argument Byte is equal to this Byte;
- a value less than 0 if this Byte is numerically less than the Byte argument;
- and a value greater than 0 if this Byte is numerically greater than the Byte argument.
$b = Byte.create(20)
print $b.compareTo(Byte.create(15))
print $b.compareTo(Byte.create(20))
print $b.compareTo(Byte.create(22))
-- the result is --
5
0
-2
| Parameters: |
| $str : | the String concept to decode. |
|
| Exceptions: |
unparsableNumberException :
(Error) | If the String does not contain a parsable byte. |
Decodes a String concept into a Byte concept.
Accepts decimal, hexadecimal, and octal numbers, in the following formats:
- [-] decimal constant
- [-] 0x hex constant
- [-] # hex constant
- [-] 0 octal constant
The result is made negative if first character of the specified String is the negative sign.
No whitespace characters are permitted in the String.
print Byte.decode("#5D")
-- the result is --
93
Returns the value of this Byte as an Integer.
$b = Byte.create(20)
print $b.getInteger
-- the result is --
20
Returns the value of this Byte as an Real.
$b = Byte.create(20)
print $b.getReal
-- the result is --
20.0
