如何在DB2中使用前导零将十进制转换为varchar？

Question

我想将除法的结果转换为DB2中的字符串 我'0.24'||'%'时的结果是'.24%' 我不明白如何准确获得输出'0.24%'

Answer 1

嗨试试像这样的事情

 case when myval<1 and myval>0 then '0' || cast(myval as char(15))  
 when myval>-1 and myval<0 then '-0' || cast(abs(myval) as char(15))
 else cast(myval as char(15)) end myvaltochar                       

Answer 2

试试这个

to_char( yourzone                                              
repeat('0', length(trim(int(abs(yourzone))))) || '.'||         
repeat('0', length(trim(                                       
INTEGER(SUBSTR(CHAR(-123.36),LOCATE(',',CHAR(yourzone))+1))))) 
    )                                                      

Answer 3

SELECT VARCHAR_FORMAT(24.0/100,'0.00')||'%' ...

如果要划分整数类型，则必须将它们转换为DOUBLE()，否则结果将为0
