Examples of org.springframework.format.number.NumberFormatter

org.springframework.format.number.NumberFormatter
A general-purpose Number formatter.
Delegates to {@link NumberFormat#getInstance(Locale)}. Configures BigDecimal parsing so there is no loss in precision. Allows configuration over the decimal number pattern. The {@link #parse(String,Locale)} routine always returns a BigDecimal. @author Keith Donald @author Juergen Hoeller @since 3.0 @see #setPattern @see #setLenient
