_byte

#byte

###Convert to an unsigned byteacter value or create an unsigned byteacter variable.

Syntax

result = byte value ;
byte variable [= value] ; 

Arguments

1. list value

A value of any type.

Return Value

byte result

• byteacter : A signed 8 bit value.

The STATUS variable is set to $ACKNOWLEDGE

When the argument is an array variable, all the elements in the array are converted, and the result will be a vector array byte result

• byteacter : A signed 8 bit value.

The STATUS variable is set to $ACKNOWLEDGE

When the argument is an array variable, all the elements in the array are converted, and the result will be a vector array

Exceptions

• %ARGUMENT: Invalid arguments. Usage: byte variable [= value] ;

• %IDENTIFIER: 'variable' argument is not a valid identifier, literal, or reference

Description

byte -128 to +127

ubyte 0 to 255

• byte and ubyte are interchangable, the sign bit is never lost.
• The ubyte format is the same as the binary format except in the manner in which the value is displayed, decimal for ubyte and hexidecimal for binary.

A byte and ubyte formats are a one-byte signed and unsigned integer, respectively. The values range from0x00 through 0xff, which in the signed byte case is between -128 and +127, and between 0 and 255 for the unsigned byte.

Examples

put byte ( 127 ) ; //== 128
put byte ( 128 ) ; //== -128
put byte ( 255 ) ; //== -1
put byte ( 256 ) ; //== 0
put byte ( 257 ) ; //== 1
