SetPrecision, really need help !

[ellyrion]

here's the thing: I must have a project ready by the day after tomorrow. It's all working except for one little thingy, I must have precision in my float. So for example when the solution is 15.4834573154 it must come 15.48 ! I tried with a mask but then I become 15.480000000 . I know it's something with SetPrecision command, but I tried everything I know and it just doesn't work :-(. Can someone help me please!!!

I'm assumming that you are using streams.

double ExpSQ_M = 1234.4583;
//OFile << setprecision(3) << ExpSq_M << endl;  // Square Meters to an output file
cout << setprecision(3) << ExpSq_M << endl;  // Square Meters

I forgot to mention that you will need to include the iomanip.h file.

or another cheap and dirty way is

float Example = 23.544566;
float Item;
int Temp = (float / .01);
Item = Temp *.01;
