不将3位数字转换为单词
不将3位数字转换为单词
提问于 2018-07-25 05:51:07
下面的代码用于将1-999之间的任何数字转换为单词。但是，代码不会将其转换为除百的倍数以外的任何3位数字。例如，它将567打印为5007。该程序还能够打印1到100之间的所有数字。请给我建议。谢谢!

在100到999之间的数字的if语句中，您可以这样写
tensDigit = Math.floor(num / 10);但是，对于数字567，Math.floor(num / 10);计算为56，这是一个没有包含在tens()函数中的数字。要解决此问题，应将tensDigit设置为
tensDigit = Math.floor(num / 10) % 10;Stack Overflow用户

很抱歉指出这一点，但你的代码很长，而且不是算法。这是一个有效的方法：
package assortie
{
import flash.display.Sprite;
public class SpellNumber extends Sprite
{
// Class constructor and tests.
public function SpellNumber()
{
super();
trace(toWords(567));
trace(toWords(7));
trace(toWords(56));
trace(toWords(19));
trace(toWords(913));
}
static private const ONES :Array = ["", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine"];
static private const TENS :Array = ["", "", "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety"];
static private const TEENS:Array = ["Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen"];
// This method converts numbers fom 1 to 999 to words.
static private function toWords(value:int):String
{
var result:String = "";
// Unexpected data cases.
if (value < 1) return "Number is out of bounds: " + value + " is zero or less.";
if (value > 999) return "Number is out of bounds: " + value + " is thousand or greater.";
// Figure out hundreds.
var aHun:int = value / 100;
if (aHun > 0)
{
// Remove hundreds from the given value.
value %= 100;
// Form the words for hundreds.
result += ONES[aHun] + " Hundred";
}
// Check if rest is teens.
if ((value > 9) && (value < 20))
{
// Add one space if result is not empty.
if (result) result += " ";
// Form the words for teens.
result += TEENS[value - 10];
// Return the result. There's nothing to do here any longer.
return result;
}
// Figure out tens.
var aTens:int = value / 10;
if (aTens > 0)
{
// Remove tens from the rest of the value.
value %= 10;
// Add one space if result is not empty.
if (result) result += " ";
// Form the words for tens.
result += TENS[aTens];
}
// Figure out the last digit.
if (value > 0)
{
// Add one space if result is not empty.
if (result) result += " ";
// Form the words for the last digit.
result += ONES[value];
}
return result;
}
}

在此条件下(num >= 100 && num <= 999)中该行的问题
tensDigit = Math.floor(num / 10);这一行的结果是11、12或13，...etc。因此，tens()函数的条件将不会得到满足。
将此行修改为：
tensDigit = Math.floor(num % 100 / 10);告诉我它有没有用。
