Sum the fields with 6 decimal places - getting only 2 decimal places as output
I used the below script to Sum up a field in a file based on some unique values. But the problem is when it is summing up the units, it is truncating to 2 decimals and not 6 decimals as in the input file (Input file has the units with up to 6 Decimals – Sample data below, when the units in the 2 rows below highlighted in red are added, I only get 2 decimal places 18.34).
I have a perl script that reports the avg time of a application call and the total number of calls. This works fine, however I would like to trim the number of decimal places reported from 12 to like 3 and I don't know how.
Any suggestions? Here is what I use to get the avg time...

QDoubleValidator(3qt)QDoubleValidator(3qt)NAME
QDoubleValidator - Range checking of floating-point numbers
SYNOPSIS
#include <qvalidator.h>
Inherits QValidator.
Public Members
QDoubleValidator ( QObject * parent, const char * name = 0 )
QDoubleValidator ( double bottom, double top, int decimals, QObject * parent, const char * name = 0 )
~QDoubleValidator ()
virtual QValidator::State validate ( QString & input, int & ) const
virtual void setRange ( double minimum, double maximum, int decimals = 0 )
void setBottom ( double )
void setTop ( double )
void setDecimals ( int )
double bottom () const
double top () const
int decimals () const
Properties
double bottom - the validator's minimum acceptable value
int decimals - the validator's maximum number of digits after the decimal point
double top - the validator's maximum acceptable value
DESCRIPTION
The QDoubleValidator class provides range checking of floating-point numbers.
QDoubleValidator provides an upper bound, a lower bound and a limit on the number of digits after the decimal point. It does not provide a
fixup() function.
You can set the acceptable range in one call with setRange(), or with setBottom() and setTop(). Set the number of decimal places with
setDecimals(). The validate() function returns the validation state.
See also QIntValidator, QRegExpValidator, and Miscellaneous Classes.
MEMBER FUNCTION DOCUMENTATION QDoubleValidator::QDoubleValidator ( QObject * parent, const char * name = 0 )
Constructs a validator object with parent parent, called name, which accepts any double.
QDoubleValidator::QDoubleValidator ( double bottom, double top, int decimals, QObject * parent, const char * name = 0 )
Constructs a validator object with parent parent, called name. This validator will accept doubles from bottom to top inclusive, with up to
decimals digits after the decimal point.
QDoubleValidator::~QDoubleValidator ()
Destroys the validator, freeing any resources used.
double QDoubleValidator::bottom () const
Returns the validator's minimum acceptable value. See the "bottom" property for details.
int QDoubleValidator::decimals () const
Returns the validator's maximum number of digits after the decimal point. See the "decimals" property for details.
void QDoubleValidator::setBottom ( double )
Sets the validator's minimum acceptable value. See the "bottom" property for details.
void QDoubleValidator::setDecimals ( int )
Sets the validator's maximum number of digits after the decimal point. See the "decimals" property for details.
void QDoubleValidator::setRange ( double minimum, double maximum, int decimals = 0 ) [virtual]
Sets the validator to accept doubles from minimum to maximum inclusive, with at most decimals digits after the decimal point.
void QDoubleValidator::setTop ( double )
Sets the validator's maximum acceptable value. See the "top" property for details.
double QDoubleValidator::top () const
Returns the validator's maximum acceptable value. See the "top" property for details.
QValidator::State QDoubleValidator::validate ( QString & input, int & ) const [virtual]
Returns Acceptable if the string input contains a double that is within the valid range and is in the correct format.
Returns Intermediate if input contains a double that is outside the range or is in the wrong format, e.g. with too many digits after the
decimal point or is empty.
Returns Invalid if the input is not a double.
Reimplemented from QValidator.
