Sylvain Pion 6601da2073 - Introduced namespace CGAL. 1999-02-19 17:17:07 +00:00
Sylvain Pion 20f1a15273 - Standard header <iostream>. 
- Added operators (double, IA) for +,-,*,/,<,>...
- Changed PRECONDITION to ASSERTION.
- Default constructor is the buggy interval [1;-1] to detect use before
  definition in the user's code.
- Fine-tuned the multiplication (once again :).
- Same for division.
- Various code looking clean up.
- Removed a useless test in CGAL_sign()'s equality case.
- About the same for CGAL_compare().
 1999-02-19 15:04:17 +00:00
Sylvain Pion eb271e36dd - += and -= rely on + and -, no redefinition (it was for speed, but...). 
- Added conditional include for Quotient<>.
 1999-02-04 13:25:13 +00:00
Sylvain Pion f4213551e7 - moved conditionnal include lines at the beginning. 1999-01-19 16:17:36 +00:00
Sylvain Pion 8ac8cdf045 - Use CGAL_square<double>(), it's here now. 1999-01-05 19:14:32 +00:00
Sylvain Pion 5464c1b10d - Fixed bug in CGAL_square(): -a*a -> a*-a. 1998-12-23 12:18:50 +00:00
Sylvain Pion 6f0cf1d2f7 - CGAL_square(double) doesn't exist yet. 1998-12-22 12:51:17 +00:00
Sylvain Pion 34f5af32c1 - Replace the expensive checks by the flag CGAL_IA_DEBUG. 1998-12-22 12:40:01 +00:00
Sylvain Pion 8924234ce8 - Added CGAL_square() for both types. 
- Rewrote the header of each function in a new style.
 1998-12-17 17:37:54 +00:00
Sylvain Pion 3443c802fa - Added lots of preconditions on the rounding mode. 1998-12-13 17:38:37 +00:00
Sylvain Pion 632645e683 - line too long fixed. 1998-12-11 11:47:01 +00:00
Sylvain Pion f82270de10 - #include <CGAL/misc.h> for CGAL_convert_to<>(). 1998-12-10 16:06:12 +00:00
Sylvain Pion d1bb64cb4a - Moved the CGAL_convert_to<>() general template here. 
(will be in kernel_basic.h normally).
 1998-12-08 17:16:34 +00:00
Sylvain Pion 6e8540613c - Renamed CGAL_to_Interval_nt*() to CGAL_convert_to<CGAL_Interval_nt*>(). 1998-12-08 13:13:42 +00:00
Sylvain Pion 2ba0dea489 - Added member function bool overlap(const IA &d). 
- Added flag CGAL_IA_NO_EXCEPTION, which prevents throwing.
 1998-12-05 16:28:17 +00:00
Sylvain Pion 65df7a8b81 - Added forgottent definition of CGAL_to_double(IA_nt). 
- Added istream operator>>(IA) (via a double).
 1998-12-01 16:39:56 +00:00
Sylvain Pion 10afe69c95 Added conditionnal #include directive for IA/IA_Fixed.h. 1998-12-01 12:54:55 +00:00
Sylvain Pion ffc2b7df51 Added CGAL_number_type_tag() 1998-12-01 12:51:38 +00:00
Sylvain Pion 4913337b50 CGAL_io_tag() added. 1998-11-30 16:03:59 +00:00
Sylvain Pion a4c088ca00 - Changed again the semantic of sqrt() when negative. 
- Made static const members for largest and smallest.
- Declared the values of {min,max}_double outside => CC accepts it now.
 1998-11-25 16:38:40 +00:00
Sylvain Pion e4b1b35ce4 - Added double member constants "min_double" and "max_double". 
- Added global constants CGAL_Interval_smallest and CGAL_Interval_largest.
- Added a template for CGAL_to_Interval_nt() and a specialisation for doubles.
 1998-11-23 15:19:19 +00:00
Sylvain Pion 1c9b971740 Use more "typedef CGAL_Interval_nt IA". 1998-11-18 16:39:59 +00:00
Sylvain Pion d5273396c5 sqrt() semantic has changed. 1998-11-18 16:30:30 +00:00
Sylvain Pion 2d75f4a70f - Passing "double" instead of "double &" seems faster, so I changed all 
concerned function prototypes.
- Moved ctor def CGAL_Interval_nt(const CGAL_Interval_nt_advanced &d) at the
  beginning of the class body so that it can be inlined.
- Redefined (grrr) friends CGAL_{abs,sign, compare, min...} for
  CGAL_Interval_nt.
- overlap_action() should maybe be redefined for CGAL_Interval_nt, but this
  should use a virtual function, so the code is ready, but I need the first
  benchmarks to activate it.
- New (undocumented for the moment) member function is_same() that does a
  "deep compare" (test equality of both bounds of 2 intervals).
- commented out the friendlyness of operator* (const double, const IA &).
 1998-11-12 16:10:42 +00:00
Sylvain Pion 04810e2dc4 - Added "typedef CGAL_Interval_nt IA;", and done some substitutions. 1998-11-05 15:22:10 +00:00
Sylvain Pion b1b92487d7 - Added specializations for the functions CGAL_{sign,compare,abs,min,max}. 
- overlap_action() returns an int(0), to shut up compiler, and provide
  a default answer, when we don't want the exception.
- The test operators now "return overlap_action();".
- One test less in operator==().
 1998-11-05 14:28:18 +00:00
Sylvain Pion 872c4c7fe1 Changed member functions is_valid() and is_finite() to be non member functions 
CGAL_is_valid(IA) and CGAL_is_finite(IA).
 1998-10-30 12:22:37 +00:00
Sylvain Pion fd6727c9a8 CGAL_to_interval_nt(double) now returns an IA_advanced. 1998-10-28 17:20:41 +00:00
Sylvain Pion 6256a74fa0 New empty member class unsafe_comparison. 
New private function overlap_action(), that throws the above exception, when
comparing unsafely.  CGAL_IA_DONT_THROW_EXCEPTION defines the behaviour at
compile time.
 1998-10-26 13:41:00 +00:00
Sylvain Pion f979f9578a Bump for 2.3: small cleanup. 1998-10-23 08:53:48 +00:00
Sylvain Pion 5a2090bde6 Changed "class" to "struct". 
Put the cast "IA_advanved -> IA" private.
Put the 2 doubles at the top of the definition.
 1998-10-22 13:23:12 +00:00
Sylvain Pion 7fa30708d0 Added for the 2 classes, the 2 operators: *(IA, double) and *(double, IA). 1998-10-21 16:51:40 +00:00
Sylvain Pion 814447927d - operator<< doesn't need to be a friend function anymore. 
- using the GNU extension optimization "Named return value".
- new protected function verify_overlap() (to clean up the comparison
  functions codes).
- operator*() and operator/() are outside the class body, so they can be made
  not inlined.
 1998-10-20 13:42:32 +00:00
Sylvain Pion 4f8701d25b 2 small comments added. 1998-10-16 14:30:50 +00:00

Sylvain Pion bfc9ee9ef3 Put the operators' code outside the class body. 
Made operator<<() a friend function, with const argument.
 1998-10-15 11:58:32 +00:00

- Corrected is_valid() when inf = sup.
 1998-10-02 11:14:06 +00:00
