public class DecimalUtils
extends java.lang.Object

Static methods for dealing with floating point numbers in string decimal form.

Method Summary

Modifier and Type	Method and Description
static java.lang.String	trimInsignificantZeros(java.lang.String floatingPointNumber) Removes trailing zeros after the decimal dot and also the dot itself if there are no non-zero digits after it.
static java.lang.String	trimInsignificantZeros(java.lang.String floatingPointNumber, char decimalSeparator, java.lang.String exponentialSeparator) Removes trailing zeros after the decimal separator and also the decimal separator itself if there are no non-zero digits after it.
static java.lang.String	trimInsignificantZeros(java.lang.String floatingPointNumber, java.text.DecimalFormatSymbols symbols) Removes trailing zeros after the decimal separator and also the decimal separator itself if there are no non-zero digits after it.

Method Detail

trimInsignificantZeros

@NonNull
public static java.lang.String trimInsignificantZeros(@NonNull
                                                               java.lang.String floatingPointNumber)

Removes trailing zeros after the decimal dot and also the dot itself if there are no non-zero digits after it. Use trimInsignificantZeros(String, DecimalFormatSymbols) instead of this method if locale specific behavior is desired.

Parameters:

floatingPointNumber - the string representing a floating point number

Returns:

the original number with trailing zeros removed

trimInsignificantZeros

public static java.lang.String trimInsignificantZeros(@NonNull
                                                      java.lang.String floatingPointNumber,
                                                      @NonNull
                                                      java.text.DecimalFormatSymbols symbols)

Removes trailing zeros after the decimal separator and also the decimal separator itself if there are no non-zero digits after it.

Parameters:

floatingPointNumber - the string representing a floating point number

symbols - the decimal format symbols

Returns:

the original number with trailing zeros removed

trimInsignificantZeros

public static java.lang.String trimInsignificantZeros(@NonNull
                                                      java.lang.String floatingPointNumber,
                                                      char decimalSeparator,
                                                      java.lang.String exponentialSeparator)

Removes trailing zeros after the decimal separator and also the decimal separator itself if there are no non-zero digits after it.

Parameters:

floatingPointNumber - the string representing a floating point number

decimalSeparator - the decimal separator

exponentialSeparator - the string used to separate the mantissa from the exponent

Returns:

the original number with trailing zeros removed
