# HEX2BIN Function

The HEX2BIN function is one of the engineering functions. It is used to convert a hexadecimal number to a binary number.

The HEX2BIN function syntax is:

HEX2BIN(number [, num-hex-digits])

where

number is a hexadecimal number entered manually or included into the cell you make reference to.

num-hex-digits is the number of digits to display. If omitted, the function will use the minimum number.

Note: if the argument is not recognised as a hexadecimal number, or contains more than 10 characters, or the resulting binary number requires more digits than you specified, or the specified num-hex-digits number is less than or equal to 0, the function will return the #NUM! error.
