The Excel BIN2HEX Function

Related Function:

Hex2Bin Function

Function Description

The Excel Bin2Hex function converts a Binary (Base 2) number into a Hexadecimal (Base 16) number.

The syntax of the function is:

BIN2HEX( number, [places] )

Where the function arguments are as follows:

number

The binary number that is to be converted to hexadecimal.

[places]

An optional argument, which specifies the number of characters that you want the returned hexadecimal number to have.

If this is greater than the minimum, the hexadecimal number will be padded out using leading zeros.

If omitted, the returned hexadecimal uses the minimum number of places.

Note that the supplied number argument must not be more than 10 characters (40 bits) long. The most significant bit of this value denotes the sign of the number and the remaining 39 bits denote the magnitude. Negative numbers are represented using two's complement notation.
