!!DESCRIPTION |

|
|
|

|
|
|
23 |
The __frexp()__ function is used to split the number |
|
|
24 |
''x'' into a normalized fraction and an exponent which is |
|
|
25 |
stored in ''exp''. |
|
|
26 |
!!RETURN VALUE |
|
|
27 |
|
|
|
28 |
|
|
|
29 |
The __frexp()__ function returns the normalized fraction. |
|
|
30 |
If the argument ''x'' is not zero, the normalized |
|
|
31 |
fraction is ''x'' times a power of two, and is always in |
|
|
32 |
the range 1/2 (inclusive) to 1 (exclusive). If ''x'' is |
|
|
33 |
zero, then the normalized fraction is zero and zero is |
|
|
34 |
stored in ''exp''. |
