Greetings!
I'd like to know how to format Real Type numbers in C++.
If I have a number like 1.23456, how can I?:
truncate it to: 1.234
round it to: 1.235
or 1.75 expressed like 1.7500
using cout.
Also, if I have one floating number like 1.2345600E05, how can I show it like an integer 123456 using cout too?

Thanks in advance!

Include <iomanip> and try cout.setf(ios::fixed) and cout.precision(n).

Thanks Krzysztof!
I followed your suggestion, and found really useful information here:
