DEC2BIN

Converts a decimal number to binary.

If this function is not available, run the Setup program to install the Analysis ToolPak. After you install the Analysis ToolPak, you must enable it by using the Add-Ins command on the Tools menu.

Syntax

DEC2BIN(number,places)

Number   is the decimal integer you want to convert. If number is negative, places is ignored and DEC2BIN returns a 10-character (10-bit) binary number in which the most significant bit is the sign bit. The remaining 9 bits are magnitude bits. Negative numbers are represented using two's-complement notation.

Places   is the number of characters to use. If places is omitted, DEC2BIN uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros).

Remarks

• If number < -512 or if number > 511, DEC2BIN returns the #NUM! error value.
• If number is nonnumeric, DEC2BIN returns the #VALUE! error value.
• If DEC2BIN requires more than places characters, it returns the #NUM! error value.
• If places is not an integer, it is truncated.
• If places is nonnumeric, DEC2BIN returns the #VALUE! error value.
• If places is negative, DEC2BIN returns the #NUM! error value.

Examples

DEC2BIN(9, 4) equals 1001

DEC2BIN(-100) equals 1110011100
