Sorry to dissapoint you, but the
doubledatatype only supports 15 digits of precision. See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/_langref_data_type_ranges.asp[^] for details. If you need more than that, you're going to have to roll your own.

It probably uses a custom datatype or a third party library containing one. Do a search on the web and you should find something suited to your needs. It may not, however, be free.

float f; double d; f = 3.1415926535897932384626433832795f; d = 3.1415926535897932384626433832795; printf( "%.32f\n", f ); printf( "%.32lf\n", d ); Output: 3.14159274101257320000000000000000 3.14159265358979310000000000000000 double has to be more precise, but the function doesnt show it!

try this:
double dFoo = 41.1325934653849974801841984193481498319048193849
char string[256];
sprintf("%d.32", dFoo);regards
