Changing number of decimal places for Unit of Measure

Question

Hi All,
I have a requirement to convert a quantity in one unit of measure to another (custom) unit of measure.
The issue is that the custom unit of measure has 4 decimal places (customer requirement). I found function module MD_CONVERT_MATERIAL_UNIT which does the trick for regular, 3 decimal places, UoM's. It won't output 4 decimal places since the output data type is EKPO-MENGE, which has 3 decimal places.
Does anyone have experience with trying to convert material's UoMs into 4 or more decimal places?
Thanks!

<b>round_f_to_15_decs</b>  round variable of type f to 15 decimals
Sometimes type F (float) is used to represent exact data (Amounts, Quantities):
if values are to big to be represented as Packed (> 31 decimals)
to significally improve performance of calculations, e.g. in statistical reports
G_DECIMAL_PLACES_GET
REPORT Z_ROUNDING .
DATA: float TYPE f,
      amount TYPE p DECIMALS 2,
      correctamount TYPE p DECIMALS 2,
      chars(5) TYPE c value '1.005'.
CLASS cl_abap_math DEFINITION LOAD.
correctamount = chars.
WRITE: / 'Exactly:', chars,
       / 'Correct Amount:',  correctamount.
float = chars.
amount = float.
skip 2.
WRITE: / '==== Usual Processing:',
       / 'Float:', float,
       / 'Decimals 3:', float DECIMALS 3,
       / 'Decimals 2:', float DECIMALS 2,
       / 'Amount:',  amount.
float = cl_abap_math=>round_f_to_15_decs( float ).
amount = float.
skip 2.
WRITE: / '==== Correct Processing:',
       / 'Float:', float,
       / 'Decimals 3:', float DECIMALS 3,
       / 'Decimals 2:', float DECIMALS 2,
       / 'Amount:',  amount.
