is_int64

This function returns whether a given variable is a 64bit integer or not.

In some cases you want to check and see what data type a variable holds in GameMaker and that's when you would use this function. It returns true or false depending on whether the value is an int64 or not.

Syntax:

is_int64(n);

Returns:

Boolean

Example:

if (!is_int64(val))
{
    show_debug_message("Not a 64bit integer!");
}

The above code checks the variable "val" to see if it contains an int64 and if it is not then it shows a message in the debug console.
