problem with constant too too large

[shin82]

Hi There!
I'm writing a C program a i have a constant very large: about 500.000.000.000
naturaly i can't use an int type or a large type.
the compiler always tell me this error:

"integer constant is too large for a "longe" type
overflow in implicit constant conversion"

and i don't know how to resolve...
someone can help me?:adore:
thx to everyone!!!
