BIN2HEX function

This article describes the formula syntax and usage of the BIN2HEX function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

Description

Converts a binary number to hexadecimal.

Syntax

BIN2HEX(number, [places])

The BIN2HEX function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

  • Number    Required. 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).

Remarks

  • If number is not a valid binary number, or if number contains more than 10 characters (10 bits), BIN2HEX returns the #NUM! error value.
  • If number is negative, BIN2HEX ignores places and returns a 10-character hexadecimal number.
  • If BIN2HEX requires more than places characters, it returns the #NUM! error value.
  • If places is not an integer, it is truncated.
  • If places is nonnumeric, BIN2HEX returns the #VALUE! error value.
  • If places is negative, BIN2HEX returns the #NUM! error value.
