hex-string-to-integer

Arguments: string &optional (start 0)end

Returns a number which is the conversion of string, which should be a string of hexadecimal digits, such as in a MD5 signature. This function is more efficient than parse-integer. md5-string and other md5 functions and other functions that do similar hashing and return hashing digests can return hex strings.

For example:

(hex-string-to-integer "deadbeef") => 3735928559

See integer-to-hex-string, which is the inverse of this function, and MD*, SHA*, HMAC, and other message digest support in miscellaneous.htm. See also usb8-array-to-hex-string and hex-string-to-integer.
