HEX2BIN
Converts a hexadecimal number to binary.
This function is only available if the Analysis AddIn is installed.
Syntax:
HEX2BIN(hexadecimalnumber; numdigits)
- returns text representing a binary number, given hexadecimalnumber, which may be text, or a number (taken to be hexadecimal although it is not).
- The binary number returned may have up to ten bits in two's complement representation; positive numbers are 0 to 111111111 (nine bits representing 0 to 511 decimal) and negative numbers 1111111111 to 1000000000 (ten bits representing -1 to -512 decimal).
- hexadecimalnumber must therefore also lie in this range, and is given in two's complement form with up to ten digits.
- numdigits is an optional number specifying the number of digits to return.
Example:
HEX2BIN("1D")
- returns 11101 as text.
HEX2BIN(10)
- returns 10000 as text. The number 10 is read as hexadecimal.
HEX2BIN("2"; 4)
- returns 0010 as text. HEX2BIN adds leading zeroes to make 4 digits.
HEX2BIN("FFFFFFFFFE")
- returns 1111111110 as text (twos complement representation of decimal -2).
