|
// * out numbers in English: 289 is formatted as "two hundred eighty-nine".

"%simplified:\n"
|
|
// negative number rule. This rule is used to format negative
|
|
// numbers. The result of formatting the number's absolute
|
|
// value is placed where the >> is.
|
|
"-x: minus >>;\n"
|
|
// faction rule. This rule is used for formatting numbers
|
|
// with fractional parts. The result of formatting the
|
|
// number's integral part is substituted for the <<, and
|
|
// the result of formatting the number's fractional part
|
|
// (one digit at a time, e.g., 0.123 is "zero point one two
|
|
// three") replaces the >>.
|
|
"x.x: << point >>;\n"
|
|
// the rules for the values from 0 to 19 are simply the
|
|
// words for those numbers
|
|
"zero; one; two; three; four; five; six; seven; eight; nine;\n"
|
|
"ten; eleven; twelve; thirteen; fourteen; fifteen; sixteen;\n"
|
|
"seventeen; eighteen; nineteen;\n"
|
|
// beginning at 20, we use the >> to mark the position where
|
|
// the result of formatting the number's ones digit. Thus,
|
|
// we only need a new rule at every multiple of 10. Text in
|
|
// backets is omitted if the value being formatted is an
|
|
// even multiple of 10.
|
|
"20: twenty[->>];\n"

"90: ninety[->>];\n"
|
|
// beginning at 100, we can use << to mark the position where
|
|
// the result of formatting the multiple of 100 is to be
|
|
// inserted. Notice also that the meaning of >> has shifted:
|
|
// here, it refers to both the ones place and the tens place.
|
|
// The meanings of the << and >> tokens depend on the base value
|
|
// of the rule. A rule's divisor is (usually) the highest
|
|
// power of 10 that is less than or equal to the rule's base
|
|
// value. The value being formatted is divided by the rule's
|
|
// divisor, and the integral quotient is used to get the text
|
|
// for <<, while the remainder is used to produce the text
|
|
// for >>. Again, text in brackets is omitted if the value
|
|
// being formatted is an even multiple of the rule's divisor
|
|
// (in this case, an even multiple of 100)
|
|
"100: << hundred[ >>];\n"
|
|
// The rules for the higher numbers work the same way as the
|
|
// rule for 100: Again, the << and >> tokens depend on the
|
|
// rule's divisor, which for all these rules is also the rule's
|
|
// base value. To group by thousand, we simply don't have any
|
|
// rules between 1,000 and 1,000,000.

|
|
// quadrillion or more are shown in numerals rather than words.
|
|
// The == token means to format (with new rules) the value
|
|
// being formatted by this rule and place the result where
|
|
// the == is. The #,##0 inside the == signs is a
|
|
// DecimalFormat pattern. It specifies that the value should
