| # Base-N & Logic Functions
> Base-N and logic functions are listed in alphabetical order below. The calculator must be in a base-N mode to access these functions. ## << (Shift left) Bitwise shift left where the MSB is lost. This is a postfix function which may be repeated as many times as required. If the value represents a floating point value with a fractional part, it is first converted to 64 bit integer for the operation. ## >> (Shift Right) Bitwise shift right where the LSB is lost. This is a postfix function which may be repeated as many times as required. If the value represents a floating point value with a fractional part, it is first converted to 64 bit integer for the operation. ## AND Performs a bitwise AND operation between two integer values. If either argument represents a floating point value with a fractional part, it is first converted to 64 bit integer for the operation and any fractional component will be lost. ## BE⇔LE Exchanges the byte order between Big Endian (network order) and Little Endian (Intel). Works with either 32 or 64 bit integers. If the value represents a floating point value with a fractional part, it is first converted to 64 bit integer for the operation and any fractional component will be lost. Example:
>     [HEX] 944
>     [BE⇔LE]
>     Displays: 4409 0000 (hex)
> BE⇔LE acts as a toggle, and pressing it again reverses the operation. ## BIN Sets the radix to binary, converting the display value as required. ## DEC Sets the radix to decimal, converting the display value as required. ## HEX Sets the radix to hexadecimal, converting the display value as required. ## KB Displays the current value as a multiple of 1024 and shows an appropriate KB, MB, GB, TB indication. Example:
>     [DEC]
>     34329232
>     [KB]
>     Displays: 32 MB
>     [KB]
>     Displays: 34329232 KB
> This operation works in a similar way to the [ENG] key and may be pressed several times to adjust the magnitude. The underlying numerical value remains unchanged. It may also be used in combination with [SHIFT]. ## NOT Performs a bitwise NOT operation on the input value. If the value represents a floating point value with a fractional part, it is first converted to 64 bit integer for the operation and any fractional component will be lost. ## OCT Sets the radix to octal, converting the display value as required. ## OR Performs a bitwise OR operation between two integer values. If either argument represents a floating point value with a fractional part, it is first converted to 64 bit integer for the operation and any fractional component will be lost. ## REM REM divides the first argument by the second, and returns the remainder. Example:
>     [DEC]
>     13 [REM] 9
>     [ENTER]
>     Displays: 4
DreamCalc handles signed input according to the rules defined for the "%" operator in C99 and C++11. The following examples illustrate this. 8 REM 7 = 1 8 REM -7 = 1 -8 REM 7 = -1 -8 REM -7 = -1 The MOD function is similar, but handles signed input differently. ## XNOR Performs a bitwise XNOR operation between two integer values. If either argument represents a floating point value with a fractional part, it is first converted to 64 bit integer for the operation and any fractional component will be lost. ## XOR Performs a bitwise XOR operation between two integer values. If either argument represents a floating point value with a fractional part, it is first converted to 64 bit integer for the operation and any fractional component will be lost.
