The BIN2HEX function converts a binary number to hexadecimal.

Syntax

=BIN2HEX(number,[places])

Note: Hexadecimal (base 16), decimal (base 10), octal (base 8), and binary (base 2) are the most commonly used numeral systems in engineering and computing. Therefore, Excel has provided functions to convert numeric values to and from each of these systems.

Arguments

Argument Description
number The binary number you want to convert

 • Number cannot contain more than 10 characters (10 bits) • The most significant bit of number is the sign bit • The remaining 9 bits are magnitude bits • Negative numbers are represented using two’s-complement notation
[places] Optional. The number of characters to use

 • If [places] is omitted, BIN2HEX uses the minimum number of characters necessary • [places] is useful for padding the return value with leading 0s (zeros)

Examples
