Log:
use lround() for map coord rounding to avoid silly things like
15.999999999999999998 rounding down to 15... whihc leads to
sometimes... odd off-by-1 expected results.
lround is C99 compliant and does not exist on Windows.
why not using the macro
#define round(x) (x<0?ceil((x)-0.5):floor((x)+0.5))
because 1. i dont have a manual page for what is NOT supported in windows's dev
envs (that's why we have you!).
in google : "msdn the_function"
Also, did you read the man page of lround ?
See
http://linux.die.net/man/3/lround
did you read the line "Compile with -std=c99" ? Is that flag passed to the
compiler ? Note that i added an m4 macro that checks if a flags is
supported by the compiler
sigh... there's no support for C99 in windows?
Hey, it's a 12 years old standard. Isn't evil supposed to cover these
differences without staying in our way? I'm not saying it should
already have "lround", but now it should be added, right?
even if it's a 12 years old standard, most of compilers don't even
implement it completely :
http://gcc.gnu.org/c99status.html
And it has already been said that vc++ aim is not to be C99 compliant.
It's not one of the purpose of the vc++ developpers.
