cpp conversion: minimal steps to fix compilation errors, not warnings

2018-12-26T09:08:53+00:00

Fix warnings found by clang with new warning flags to be added in later commit

2018-05-30T09:48:28+00:00

Fixes consist in:
- no use of comma operator for multi statement purpose
- avoid confusing comma in for loops first and third clauses
- avoid implicit long to int casts by storing to long, or explicit bound checking before cast

Handle double to int typecasts in ISEA better

2018-05-24T13:04:36+00:00

Originally the code was doing double to int conversions like

    y = (int)(x + 0.5)

which results in rounding when typecasting. In an earlier attempt to
avoid buffer overflows in integer typecasts this was changed to

    y = lround(x + 0.5)

which doesn't give the origial results. We fix that here by instead
doing

    y = lround(x)

It is safe to so as long as x is positive.

ISEA_STATIC -> static (#995)

2018-05-13T15:00:40+00:00

As this is a part of PROJ, having these functions possibly not static
is confusing.  Time to declare this is just a part of PROJ.

Replace int typecasts with calls to lround to avoid bad conversions on NaN input. Added test to check for those cases.
