Function name:
BIN2HEX

Category:
Add-in

Summary:
Converts a binary number (base-2) to its hexadecimal (base-16) equivalent. The input binary number must correspond to a decimal number d in the range -512 ≤ d < 512.

Syntax:
BIN2HEX(Number[; Places])

Returns:
Returns a text string comprising up to 10 hexadecimal characters (0…9 or A…F), which is the hexadecimal number in two’s complement form that corresponds to the specified binary number.

Arguments:
Number is a string or a number, or a reference to a cell containing one of those types, which gives the binary number that is to be converted to hexadecimal. The binary number must comprise only the digits 0 and 1, and must be no more than 10 digits long.

Places is an integer in the range 1 to 10, or a reference to a cell containing that value, which is the number of characters that should be returned for a positive Number. Places is ignored for negative values of Number, when BIN2HEX always returns 10 characters. The default for positive values of Number is for the returned string to occupy as many characters as necessary to accommodate the hexadecimal representation, but you can set the value of Places to add leading zeroes where necessary.


 * Number should use the standard two's complement representation, so that positive numbers are binary 0 to 111111111 (0 to 511 decimal) and negative numbers are binary 1111111111 to 1000000000 (-1 to -512 decimal). Negative numbers must be 10 digits long with the leftmost bit set to 1; positive numbers can comprise less than 10 digits.
 * If Number does not specify a valid binary number, then BIN2HEX reports an invalid argument error (Err:502). This may arise, for example, if Number contains more than 10 characters or if it contains any character other than the digits 0 and 1.
 * If Number is a string comprising no characters, or a reference to an empty cell, BIN2HEX returns 0 (possibly with leading zeroes, depending on the value of Places).
 * Although the content of Number appears to be decimal, BIN2HEX will interpret it correctly.
 * If Places is non-numeric, then BIN2HEX reports an invalid argument error (Err:502).
 * If Places is a non-integer value, then BIN2HEX truncates it to an integer.
 * If, after any truncation, Places is less than 1 or greater than 10, BIN2HEX reports an invalid argument error (Err:502).
 * If Number is positive and Places is less than the minimum number of characters required to accommodate the hexadecimal representation of Number, then BIN2HEX reports an invalid argument error (Err:502).
