The Excel DEC2HEX function converts a decimal number to a hexadecimal number.

Syntax and arguments

Formula syntax

DEC2HEX(number, [places])


  • Number: Required, the decimal integer number that needed to be converted to a hexadecimal number. If the argument number is a decimal number (no whole number), it will be truncated to an integer.
  • Places: Optional, the number that specifies the number of characters of the result. If it is greater than the minimum, the result number will be padded out using leading zeros, such as DEC2HEX (1,5) returns 00001. If it is omitted, DEC2HEX used the minimum number of characters necessary. If the argument number is negative, the places value will be ignored by DEC2HEX function, and returns a 10-character (40 bits) hexadecimal number. The first bit indicates whether the number is positive or negative, and the remaining bits indicate the magnitude of the number. If argument places is a decimal number, it will be truncated to an integer.
