    Cool Clarification: Type cast double to int

    Hi Guys,

    I'm using
    Code:
    static_cast<int>
    on a double.

    Can someone please correct me if I'm wrong etc...

    But does this just remove everything after the decimal point??

    e.g. If my double was 1.99999
    Then after this operation it would give me an integer of 1?

    Cheers,

    That's C++, not C. The result will be rounded down, but it does not change the value of the variable itself.
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge
