BIN2HEX
Converts a binary number to hexadecimal.
This function is only available if the Analysis AddIn is installed.
Syntax:
BIN2HEX(binarynumber; numdigits)
- returns text representing a hexadecimal number, given binarynumber, which may be text, or a number containing only digits 1 and 0 (thus the number appears to be binary although it is not).
- binarynumber 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)
- numdigits is an optional number specifying the number of digits to return.
- If binarynumber is negative, BIN2HEX returns ten hexadecimal digits, representing the hexadecimal number in twos complement form.
Example:
BIN2HEX("11101")
- returns 1D as text.
BIN2HEX(11101)
- returns 1D as text. The number 11101 has only 1 and 0 digits, and may be read as binary.
BIN2HEX("110100110"; 4)
- returns 01A6 as text. BIN2HEX adds a leading zero to make 4 digits.
BIN2HEX("1111111110")
- returns FFFFFFFFFE as text (twos complement representation of decimal -2).
