64 bits data type

Jump to solution

Hi everybody,

 

I'm working with SP605 and Microblaze processor and i need to use 64 bits data type for CRC-32 implementation. ¿Does it exist? I don't find any information about this...

 

Thanks in advance!!

Typically the "long long" datatype is a 64 bit integer - whereas "double" is a 64 bit floating point.

In any case though, you can test the size of the datatypes with the sizeof() function to be sure...
