FLOATDEC returns a FLOAT DEC value with precision derived from
the source unless explicitly specified as a parameter to the function.
>>-FLOATDEC(x-+----+-)----------------------------------------->< '-,p-'
- x
- Expression.
- p
- Restricted expression that specifies the total number of digits in the result. It must not exceed the implementation limit.
If p is omitted, the precision of the result is determined from the source according to this table:
| source | result |
|---|---|
| FIXED BIN(p,q) | FLOAT DEC(r) |
| FIXED DEC(p,q) | FLOAT DEC(p) |
| FLOAT BIN(p) | FLOAT DEC(r) |
| FLOAT DEC(p) | FLOAT DEC(p) |
| BIT | FLOAT DEC(r) |
| CHAR, GRAPHIC or WIDECHAR | FLOAT DEC(N) |
