GetByte0, GetByte1, GetByte2, GetByte3 Function

Purpose

The GetByte functions read a byte from a 32-bits value.

Syntax

Byte = GetByte0(value)

Byte = GetByte1(value)

Byte = GetByte2(value)

Byte = GetByte3(value)

value:aexp of 4-bytes

Description

GetByte0 reads the first byte (MSB - most significant byte) of a value of a 32-bits data type.

GetByte1 reads the second byte of a value (2nd MSB).

GetByte2 reads the third byte of a value (3rd MSB).

GetByte3 reads the fourth byte of a value (LSB - least significant byte).

Dim a% = $01020304

Example

Example 1

OpenW 1

Local a As Single, byte0%, byte1%, x%

Local byte2%, byte3%

a = 222266 * 456 + 97 * 35786

byte0% = GetByte0(a)

byte1% = GetByte1(a)

byte2% = GetByte2(a)

byte3% = GetByte3(a)

Print a, byte0%, byte1%, byte2%, byte3%

Example 2

OpenW 1

Local byte_hi0%, byte_hi1%, byte_hi2%, x%

Local byte_hi3%, byte2%, byte3%, a_int%

Local a As Large, byte0%, byte1%

a = _maxLarge

a_int% = HiLarge( a)

byte0% = GetByte0(a)

byte1% = GetByte1(a)

byte2% = GetByte2(a)

byte3% = GetByte3(a)

Print a, byte0%, byte1%, byte2%, byte3%

byte_hi0% = GetByte0(a_int%)

byte_hi1% = GetByte1(a_int%)

byte_hi2% = GetByte2(a_int%)

byte_hi3% = GetByte3(a_int%)

Print a_int%, byte_hi0%, byte_hi1%, byte_hi2%, byte_hi3%

Print Hex$(a)
