The arguments for the BIN2HEX function are:
Argument Required? Description
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).
#3)
A few more things:
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.
