Engineering - DEC2BIN Function

Description

The DEC2BIN function converts a decimal number to binary.

Syntax

DEC2BIN (number, [places])

Arguments

Argument	Description	Required/ Optional
number	The decimal integer you want to convert. If number is negative, valid place values are 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.	Required
places	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).	Optional

Argument

Description

Required/ Optional

number

The decimal integer you want to convert.

If number is negative, valid place values are 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.

Required

places

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).

Optional

Notes

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 zero or negative, DEC2BIN returns the #NUM! error value

Applicability

Excel 2007, Excel 2010, Excel 2013, Excel 2016
