|

- IEEE 1003.1 ceil function.
|

-
|
||||
- PowerPC64 long double uses the IBM extended format which is
|
||||
- represented two 64-floating point double values. The values are
|
||||
- non-overlapping giving an effective precision of 106 bits. The first
|
||||
- double contains the high order bits of mantissa and is always ceiled
|
||||
- to represent a normal ceiling of long double to double. Since the
|
||||
- long double value is sum of the high and low values, the low double
|
||||
- normally has the opposite sign to compensate for the this ceiling.
|
||||
-
|
||||
- For long double there are two cases:
|
||||
- 1) |x| < 2**52, all the integer bits are in the high double.
|
||||
- ceil the high double and set the low double to -0.0.
|
||||
- 2) |x| >= 2**52, ceiling involves both doubles.

||||
