FDEC() Function - Convert Binary Float to Decimal
Syntax
FDEC(string{,ERR=lineref})
Description
For BBj-specific information, see the FDEC() Function - BBj.
The FDEC() function accepts an 8-byte floating point format and returns its decimal numeric equivalent.

String in 8-byte floating point format to be converted to decimal. |
|
ERR=lineref |
Branch to be taken if an error occurs during execution. |
Because the IEEE 64-bit standard defines a range of magnitudes greater than that of PRO/5, it is possible to get an overflow error (!ERROR=40) for extremely large values. In addition, IEEE defines a precision of approximately 16 digits; therefore, there may be some loss of precision going to PRO/5's 16-digit precision. Finally, commonly used "special values," such as NA or ERR in a spreadsheet generate an !ERROR=40. Check for these values by using a simple string compare.
FDEC() expects IEEE values in natural left-to-right ordering. Therefore, use care when communicating with other applications, such as spreadsheets, because of possible byte/word ordering differences on different systems and different software packages. See also SWAP.
The FBIN() function is complementary to the FDEC() function.
