Argument Required? Description
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).

If DEC2HEX requires more than places characters, it returns the #NUM! error value.
If places is not an integer, it is truncated.
