Method Detail

format

public String format(double x)

Formats a number with the configured number of decimals. For better performance best use format(double, StringBuffer) against a re-used StringBuffer

Parameters:

x -

sb -

format

public StringBuffer format(double x,
                           StringBuffer sb)

Formats a number with the configured number of decimals

Parameters:

x -

sb -

getMaximumFractionDigits

public int getMaximumFractionDigits()

Returns the maximum number of digits allowed in the fraction portion of a number.

Returns:

the maximum number of digits.

setMaximumFractionDigits

public void setMaximumFractionDigits(int maxDigits)

isForcedDecimal

public boolean isForcedDecimal()

Returns the force decimal flag, see setForcedDecimal(boolean)

Returns:

isPadWithZeros

public boolean isPadWithZeros()

setForcedDecimal

public void setForcedDecimal(boolean forcedDecimal)

When set to true, forces decimal representation of numbers, otherwise allows scientific notation too (for very large of very small numbers). False by default.

Parameters:

forcedDecimal -

setPadWithZeros

public void setPadWithZeros(boolean pad)
