Question

嗨，我是猪编程的新手。我有一个csv文件和选项卡作为分隔符。在我的价格栏中，我有lacs和crores。它看起来像40.85 Lacs，36.73 Lacs，2.01 cr。我想像这样转换成十进制

40.85 Lacs - 40,85,000
36.73 Lacs - 36,73,000
2.01 cr - 2,01,00000

我尝试了以下代码：

a = LOAD '/user/user1/input/city/cityname.CSV' using PigStorage('|') as (SourceWebSite:chararray,PropertyID:chararray,ListedOn:chararray,ContactName:chararray,TotalViews:int,Price:chararray,PriceperArea:chararray,NoOfBedRooms:int,NoOfBathRooms:int,FloorNoOfProperty:chararray,TotalFloors:int,Possession:chararray,BuiltUpArea:chararray,Furnished:chararray,Ownership:chararray,NewResale:chararray,Facing:chararray,title:chararray,PropertyAddress:chararray,NearByFacilities:chararray,PropertyFeatures:chararray,Sellerinfo:chararray,Description:chararray);
DUMP a;
b = FOREACH a GENERATE Price;
dump b;
c = FILTER b BY (Price matches '.*Lacs.*');
d = FOREACH c GENERATE Price * 10000.0,SUBSTRING(Price,00000);
d = foreach c generate Price,TOKENIZE(REPLACE(Price,'.','')) AS e;

我在这里挣扎了两天。任何帮助将不胜感激。

Answer 1

使用REGEX_EXTRACT获取值的第一部分，直到空白，将其转换为BigDecimal，然后将其相乘。使用此输入数据，例如：

(40.85 Lacs,1)
(36.73 Lacs,2)
(2.01 cr,3)

以下代码可行：

A = load 'data' using PigStorage(';');
B = foreach A generate (bigdecimal)REGEX_EXTRACT($0, '(.*) (.*)', 1) * 1000000;
dump B;

输出结果为：

(40850000.00)
(36730000.00)
(2010000.00)

无法将char数组转换为猪的十进制数
