This encompasses a broad area, 16*61c4878aSAndroid Build Coastguard Workerbut since the C++ standard library provides many mathematical utilities already, 17*61c4878aSAndroid Build Coastguard Workerthis module is not anticipated to be too large. If the module does grow 18*61c4878aSAndroid Build Coastguard Workersubstantially, some features may be moved to other modules (e.g. 19*61c4878aSAndroid Build Coastguard Worker``pw_statistics``). 20*61c4878aSAndroid Build Coastguard Worker 21*61c4878aSAndroid Build Coastguard Worker**What does NOT belong in this module?** 22*61c4878aSAndroid Build Coastguard Worker 23*61c4878aSAndroid Build Coastguard Worker- Features available in the C++ standard library (``<cmath>``, ``<numeric>``, 24*61c4878aSAndroid Build Coastguard Worker ``<bit>``, etc.) should not be duplicated. 25*61c4878aSAndroid Build Coastguard Worker- Pseudo-random number generation belongs in :ref:`module-pw_random`. 26*61c4878aSAndroid Build Coastguard Worker- Data integrity checking belongs in :ref:`module-pw_checksum`. 27*61c4878aSAndroid Build Coastguard Worker- Bit / byte manipulation belong in :ref:`module-pw_bytes`. 28*61c4878aSAndroid Build Coastguard Worker 29*61c4878aSAndroid Build Coastguard Worker----------------- 30*61c4878aSAndroid Build Coastguard WorkerC++ API reference 31*61c4878aSAndroid Build Coastguard Worker----------------- 32*61c4878aSAndroid Build Coastguard Worker 33*61c4878aSAndroid Build Coastguard Workerpw_numeric/integer_division.h 34*61c4878aSAndroid Build Coastguard Worker============================= 35*61c4878aSAndroid Build Coastguard Worker.. doxygenfunction:: pw::IntegerDivisionRoundNearest 36
