PUBLIC INT64 And (int64, int64)
Purpose: Performs a bitwise AND operation
Notes:

Parameters:
piValue1 INT64
The first operand
piValue2 INT64
The second operand
Returns INT64
The resulting value
Top

PUBLIC INT64 Hex2Int (character)
Purpose: Converts a hexdecimal string expression into the Integet value
Notes:

Parameters:
pcHex CHARACTER
The hexadecimal value
Returns INT64
The resulting integer value
Top

PUBLIC CHARACTER Int2Hex (int64)
Purpose: Converts a hexdecimal string expression into the Integet value
Notes:

Parameters:
piInt INT64
The hexadecimal value
Returns CHARACTER
The resulting integer value
Top

PUBLIC LOGICAL IsNumber (character)
Purpose: Returns if the provided string can be converted into an integer number
Notes:

Parameters:
pcString CHARACTER
The string to verify
Returns LOGICAL
Logical value indicating if the value can be converted into a number
Top

PUBLIC INT64 Not (int64)
Purpose: Performs a bitwise NOT operation
Notes:

Parameters:
piValue INT64
The value to be processed
Returns INT64
The resulting value
Top

PUBLIC INT64 Or (int64, int64)
Purpose: Performs a bitwise OR operation
Notes:

Parameters:
piValue1 INT64
The first operand
piValue2 INT64
The second operand
Returns INT64
The resulting value
Top

PUBLIC INTEGER Percentage (integer, integer)
Purpose: Returns the percentage of the provided value to the provided whole
Notes: The result will never exceed 100%, even when the value is higher than
the whole

Parameters:
piValue INTEGER
The (smaller) value
piWhole INTEGER
The whole (100%) value
Returns INTEGER
The percentage value
Top

PUBLIC INT64 Roundup (decimal)
Purpose: Rounds up a number if it's not already an integer
Notes: Negative numbers will actually be rounded down, i.o.w. Roundup (-1.5)
will return -2, so that the absolute value will be rounded up

Parameters:
pdeNumber DECIMAL
The number to round up
Returns INT64
The rounded value
Top

PUBLIC INT64 Xor (int64, int64)
Purpose: Performs a bitwise XOR operation
Notes:

Parameters:
piValue1 INT64
The first operand
piValue2 INT64
The second operand
Returns INT64
The resulting value
