Please elaborate on the nature of the modification. Will the case always be as in your example, lowest order bit, which is guaranteed to be zero, toggled to 1 (essentially, just adding 1 to the byte's value)? Or, is the solution required to work on other bits in a byte? And, if the byte is already 1, should it be left unchanged, or should it be toggled to zero? I assume, regardless, that unlike addition, there should be no carry over into higher order bits?

NAME
_decodebinary64(), _decodebinary128(), _decodebinary32() - decode binary-encoded decimal data SYNOPSIS
DESCRIPTION
There are two standard bit-encodings for decimal floating-point data: binary and decimal. Both encoding provide exactly the same data (analogous to big endian and little endian encodings). The HP-UX decimal floating-point types use the binary encoding. The function decodes x, interpreted as a binary-encoded 64-bit decimal datum, into the encoding for is a version of it takes a argument and returns a result. is a version of it takes a argument and returns a result. These math functions are supported for HP-UX 11i Version 3 September 2008 Update and forward. USAGE
