Method Detail

format

public static java.lang.String format(double d)

Convert a double precision number to a string with 2 digits after the decimal point. Invoking format(d) is equivalent to invoking format(d,2). See format(double,int) for more information.

Parameters:

d - the double precision number to format

Returns:

the formatted string

format

public static java.lang.String format(double d,
                                      int iNumFracDigits)

Return a string for displaying the specified number, with a variable number of digits after the decimal point. For numbers less than -10000 and greater than +100000, and for numbers between -0.1 and +0.1, a scientific notation format is used. For all other numbers a fixed point format is used. If the number is 0.0, the string "0.0" is returned.

Parameters:

d - the double precision number to format

iNumFracDigits - the number of digits after the decimal point

Returns:

the formatted string

format

public static java.lang.String format(double d,
                                      int iNumFracDigits,
                                      boolean useE)

Return a string for displaying the specified number, with a variable number of digits after the decimal point. If useE is false, a fixed point format is usd for all numbers. If useE is true, then for numbers less than -10000 and greater than +100000, and for numbers between -0.1 and +0.1, a scientific notation format is used.

Parameters:

d - the double precision number to format

iNumFracDigits - the number of digits after the decimal point

useE - if true use scientific notation for small and large numbers

Returns:

the formatted string

formatE

public static java.lang.String formatE(double d,
                                       int iNumFracDigits)

Return a string for displaying the specified number, with a variable number of digits after the decimal point, using scientific notation.

Parameters:

d - the double precision number to format

iNumFracDigits - the number of digits after the decimal point

Returns:

the formatted string

toBinString

public static java.lang.String toBinString(short s)

toHexString

public static java.lang.String toHexString(short s)
