NAME
_encodebinary64(), _encodebinary128(), _encodebinary32() - encode 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 encodes x as a binary-encoded 64-bit decimal datum. 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
To use any of these functions, compile with the option. Make sure your program defines and then includes Link in the math library by specifying or on the linking command line. For more information, see the at the following site: RETURN VALUE
