ABAP 数值四舍五入函数

DATA : dat  TYPE p DECIMALS 9 VALUE 12.5445 ,
       dat1 TYPE p DECIMALS 9 .
 
DATA   dat2 TYPE p DECIMALS 9 VALUE 12.540.
 
* 方法一
CALL FUNCTION HR_NZ_ROUNDING_DECIMALS
  EXPORTING
    value_in                 = dat
    conv_dec                 = 2      " 设置保留几位小数
  IMPORTING
    value_out                = dat1
  EXCEPTIONS
    no_rounding_required     = 1
    decimals_greater_than_10 = 2
    rounding_error           = 3
    OTHERS                   = 4.
 

* 方法二
CALL FUNCTION ROUND
  EXPORTING
    decimals      = 0       " 保留多少位小数
    input         = dat2
    sign          = +     " + 向上取舍 - 向下取舍 (负数也一样)
  IMPORTING
    output        = dat1    " 输出返回结果
  EXCEPTIONS
    input_invalid = 1
    overflow      = 2
    type_invalid  = 3
    OTHERS        = 4.
