i have number in hexadecimal: ffffffffffff and need save it, used double double a=0xffffffffffff; but need print , don't know how to. each time use %f , %d , %x , doesn't print value of it; need print ffffffffffff . code: int main() { double a=0xffffffffffff; printf("%x\n",a); printf("%d\n",a); printf("%x\n",a); printf("%f\n",a); return 0; } the true value %f ; returns decimal value of hexadecimal — returns this: ffffffe0 -32 ffffffe0 281474976710655.000000 with need change hexadecimal string, compare it, because have ffffffffffff in string , need compare both. if can't printf it, neither sprintf work. that's integer, , long one. don't use double store such value, that's floating-point. just use: unsigned long long temp = 0xffffffffffffull; you have 12 hexadecimal digits, number needs @ least 12 * 4 = 48 bits. platforms should have unsigned long long ...

the documentation content handlers in orchard mentions lifecycle events ( http://docs.orchardproject.net/documentation/understanding-content-handlers ). most events self explanatory, wondering if can tell me differences between onactivated , oninitializing , , onloading ? in firing order: onactivated - content item object hierarchy has been created, not yet fetched db used preparing content part further usage. eg. setting getters , setters lazy loaded objects, setting delegates etc. think of of "constructor" given part. oninitializing - content item object hierarchy has been created, not yet fetched db. used setting initial/default property values given part. onloading - content item loaded db. used various things. fired if item exists in database , loaded. orchard core uses event set lazy loaders part records. onloaded - content item has been loaded db used various things. fired if item exists in database , record loaders have been set. can ...

a few scipy functions (like scipy.ndimage.interpolation.geometric_transform ) can take pointers c functions arguments avoid having call python callable on each point of input array. in nutshell : define function called my_function somewhere in c module return pycobject &my_function pointer , (optionally) void* pointer pass global data around the related api method pycobject_fromvoidptranddesc , , can read extending ndimage in c see in action. i interested in using cython keep code more manageable, i'm not sure how should create such object. any, well,... pointers? just in cython same thing in c, call pycobject_fromvoidptranddesc directly. here example link ported cython: ###### example.pyx ###### libc.stdlib cimport malloc, free cpython.cobject cimport pycobject_fromvoidptranddesc cdef int _shift_function(int *output_coordinates, double* input_coordinates, int output_rank, int input_rank, double *shift_data): cdef double shift =...

in oracle 10g, have table no exact duplicates, many similar rows. ok, want delete rows 1 specific criteria in collection of similar rows. criteria multiple accounts associated 1 practice_name. delete records null acct value when there multiple accounts practice_name. however, if there 1 instance of practice_name, , acct null, want preserve record. sample data: acct practice_name state phone ======================================= null pract1 mi 111-1111 1523 pract1 mi 111-1111 6824 pract1 mi 111-1111 null pract2 mi 222-2222 8945 pract2 mi 222-2222 null pract3 mi 333-3333 1486 pract4 mi 444-4444 this result like: acct practice_name state phone ======================================= 1523 pract1 mi 111-1111 6824 pract1 mi 111-1111 8945 pract2 mi 222-2222 null pract3 mi 333-3333 1486 ...
