Detailed Description

Wrapper for a double precision number, for formatted ostream output.

An Dbl object has a double precision numerical value, as well as members (width and precision) that control its output format. The << operator for an Dbl object uses the specified width and precision. The double precision number, the width and the precision may all be specified as parameters to one of several constructors. Values of width and precision that are not specified as parameters of a constructor are set within the constructor to default values given by Format::defaultWidth() and Format::defaultPrecision(), respectively.

A Dbl object may be passed to an ostream as a temporary object. For example, the expression:

std::cout << Dbl(2.0) << Dbl(3.0, 15, 8) << std::endl;

Util::Dbl::Dbl

Dbl()

Default constructor.

Definition: Dbl.cpp:17

outputs the number 2.0 using the default width and precision, followed by the number 3.0 in a field of minimum width 15 and precision 8.
