What is the best field type for currency calculations?

Question

Hiya,
I am doing a load of currency calculations e.g. here's one line of it
The 'Total' fields I am using for doing/totalling my calculations has been defined as a local variable that reference an amount field setup in the data dictionary as:
So in my program I am using these 2 decimal field.
Of course I now realize this is a problem, as lots of rounding occurs and my values are way out when you deal with amounts in the millions.
Does anyone know what type of variable they think is best for doing currency calculations?
And could you provide a simple example?
Many thanks!

Hello Robert,
I guess you can go ahead with ATFLV, incase if you want to display as a currency, you can use the function module  KKEK_CONVERT_FLOAT_TO_CURR.
DATA: c_lv_float TYPE ATFLV VALUE '4.4500000000000000E+02',
      c_lv_curr TYPE WAERS VALUE 'EUR',
      c_lv_currval TYPE NETWR_AP.
CALL FUNCTION 'KKEK_CONVERT_FLOAT_TO_CURR'
  EXPORTING
    float_imp          = c_lv_float
    curr_imp            = c_lv_curr
IMPORTING
  CURR_FIELD_EXP      = c_lv_currval
EXCEPTIONS
  OVERFLOW            = 1
  OTHERS              = 2.
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
WRITE:/ c_lv_currval.
Output: 445,00
