wxLongLong defines all usual arithmetic operations such as addition,
subtraction, bitwise shifts and logical operations as well as multiplication
- and division (not yet for the machines without native @e long long). It
- also has operators for implicit construction from and conversion to the native
+ and division (not yet for the machines without native @e long long).
+ It also has operators for implicit construction from and conversion to the native
@e long long type if it exists and @e long.
You would usually use this type in exactly the same manner as any other
If a native (i.e. supported directly by the compiler) 64 bit integer type was
found to exist, @e wxLongLong_t macro will be defined to correspond to it.
Also, in this case only, two additional macros will be defined:
- wxLongLongFmtSpec() for printing 64 bit integers
- using the standard @c printf() function (but see also
- wxLongLong::ToString for a more portable solution) and
- wxLL() for defining 64 bit integer compile-time constants.
+ - wxLongLongFmtSpec() for printing 64 bit integers using the standard @c printf()
+ function (but see also wxLongLong::ToString for a more portable solution);
+ - wxLL() for defining 64 bit integer compile-time constants.
