# DEC2HEX function

This article describes the formula syntax and usage of the DEC2HEXfunction in Microsoft Excel.

## Description

Converts a decimal number to hexadecimal.

## Syntax

DEC2HEX(number, [places])

The DEC2HEX function syntax has the following arguments:

• Number    Required. The decimal integer you want to convert. If number is negative, places is ignored and DEC2HEX returns a 10-character (40-bit) hexadecimal number in which the most significant bit is the sign bit. The remaining 39 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, DEC2HEX uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros).

## Remarks

• If number < -549,755,813,888 or if number > 549,755,813,887, DEC2HEX returns the #NUM! error value.

• If number is nonnumeric, DEC2HEX returns the #VALUE! error value.

• If DEC2HEX requires more than places characters, it returns the #NUM! error value.

• If places is not an integer, it is truncated.

• If places is nonnumeric, DEC2HEX returns the #VALUE! error value.

• If places is negative, DEC2HEX returns the #NUM! error value.
