rounding all numbers in program

[Maurader]

I have a program where I need to round almost every number to 6 decimal places. If i create a function to do this, the code gets very messy. Is there an alternate method?

 

[Guest_imported]

create a class that wraps a float.

 

[Maurader]

can u elaborate a little bit?

I know you can manipulate output precision using std::setprecision( int ) found in iomanip if that helps.

You can also calculate it like this:

double yourNumber,
numberAfterRounding,
precision = 6;

numberAfterRounding =
floor( yourNumber * pow( 10, precision ) + .5 )
/ pow( 10, precision );


Note: include cmath.
