Detailed Description

This class provides some printing and cropping utilities.

The class is used to provide some formatting options for printing out real numbers to files and to standard output. Specifically, it can make sure that a max and min field width is honored when conducting IO of numbers and strings. Basically, it's the spot to house all wrappers around commonly used printing facilities.

It can also handle cropping of numbers below a certain decade level. This is useful for IO for testing purposes. For example, if you don't care about anything below 1.0E-20, you can set up the IO so that it won't print out any digits below 1.0E-20, even digits that are in numbers greater than 1.0E-20. In other words the number

1.12345E-19

would be cropped to the value

1.1000E-19

The class wraps around a single std::ostream class. Its cropping functions are also available as a "double" conversion utility.

Deprecated:: To be removed in Cantera 2.2.

Constructor & Destructor Documentation

PrintCtrl	(	std::ostream &	coutProxy = `std::cout`,
		int	Ndec = `-1000`,
		CROP_TYPE	ctlocal = `CT_ON`
	)

Constructor.

This also serves to initialize the ticks within the object

Parameters

coutProxy	This is a reference to the ostream to use for all IO from ths object.
Ndec	value of Ndec. Defaults to -1000, i.e., no decade cropping
ctlocal	The default is to turn on cropping all the time.

Member Function Documentation

void pr_de	(	const double	d,
		int	sigDigits = `-1`,
		const int	wMin = `-1`,
		const int	wMax = `-1`
	)

Print a double using scientific notation.

Prints a double using scientific notation in a fixed number of spaces.

The precision of the number will be adjusted to fit into the maximum space.

Parameters

d	double to be printed
sigDigits	Number of significant digits (-1 = default, means to use the default number for the object, which is initially set to 13.
wMin	Minimum number of spaces to print out
wMax	Maximum number of spaces to print out

void pr_de_c10	(	const double	d,
		int	sigDigits = `-1`,
		const int	wMin = `-1`,
		const int	wMax = `-1`
	)

Print a double using scientific notation cropping decade values.

Prints a double using scientific notation in a fixed number of spaces. This routine also crops number below the default decade level.

The precision of the number will be adjusted to fit into the maximum space.

Parameters

d	double to be printed
sigDigits	Number of significant digits (-1 = default, means to use the default number for the object, which is initially set to 13.
wMin	Minimum number of spaces to print out
wMax	Maximum number of spaces to print out

double cropSigDigits	(	const double	d,
		int	sigDigits
	)		const

Crop a double at a certain number of significant digits.

This routine will crop a floating point number at a certain number of significant digits. Note, it does rounding up of the last digit.

Parameters

d	Double to be cropped
sigDigits	Number of significant digits example: d = 1.0305E-15; nsig = 3; This routine will return 1.03E-15

double cropAbs10	(	const double	d,
		const int	nDecades
	)		const

Crop a double at a certain decade level.

This routine will crop a floating point number at a certain decade lvl. In other words everything below a power of 10^Ndec will be deleted. Note, it does rounding up of the last digit.

Parameters
