Writing floats to a binary file in C++ | Equivalent of Java's DataOutputStream.writeFloat() -

-

i'm porting code java c++ , need write floats binary file. in java use dataoutputstream.writefloat(). how do in c++?

i tried method doesn't work:

std::ofstream out; out.open(somepath, std::ios::out | std::ios::binary);  float f = 0.5; out.write(reinterpret_cast<const char*>(&f), sizeof(float));

java's default behaviour write files (and other data streamed io) in big endian. c++ writes files in native format. on standard x86-derived pc native little endian, 0.5 get:

0x00 00 00 3f in c++

and

0x3f 00 00 00 in java.

in order write files can read both, have establish endian output files use , 1 of programs have reverse endian.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
