Class PrintPrecision

java.lang.Object

imagingbook.common.math.PrintPrecision

public abstract class PrintPrecision
extends Object

This class holds settings to control the precision when printing floating-point numbers, used in particular by various toString() methods for vectors and matrices defined in class Matrix (mainly for debugging).

• Constant Field Values

Method Details

reset

public static void reset()

Reset print precision to the default value (DefaultPrecision).

set

public static void set(int nDigits)

Set print precision to the specified number of digits. For example, with nDigits = 5 the resulting element format string is "%.5f". If a value ≤0 is specified, the scientific float format string "%e" is used.

Parameters:

nDigits - the number of digits to be used

get

public static int get()

Returns the current print precision (number of digits).

Returns:

the current number of digits

getFormatStringFloat

public static String getFormatStringFloat()

Returns the floaing-point format string for the current print precision (to be used in String.format(String, Object...), for example "%.6f" if print precision is set to 6, or "%e" when precision ≤0.

Returns:

the format string
