我遇到了從oracle讀取浮動的問題。 我有下面的代碼片段:閱讀oracle後錯誤的jython float精度錯誤
sqlstr='select prio from tabletest'
statement = None
if connection is not None:
try:
statement = connection.prepareStatement(sqlstr)
if connection is not None:
rs = statement.executeQuery()
if rs is not None:
#statement.closeOnComplete()
while (rs.next()):
NWW = rs.getFloat(1)
print (NWW)
rs.close()
else:
statement.close()
except:
pass
finally:
connection.close()
這讓我這個:
0.5
0.5
0.5
0.20000000298
0.5
0.990000009537
0.5
0.5
0.699999988079
,但我在DB的實際數據是這樣的:
0,5
0,5
0,5
0,2
0,5
0,99
0,5
0,5
0,7
分貝定義爲:
CREATE TABLE "SYSTEM"."tabletest"
( "NWW" NUMBER(12,8)
) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING
STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
TABLESPACE "SYSTEM" ;
,正如你所看到的,浮球只有精確的prio = 0.5 ...有什麼選擇,我可以設置浮體精確?
感謝, E.
