ABAP trick for converting a floating point number to a packed field

You just assign the type f field to a type p field. You must specify the number of decimal places and the size of the packed field, and you should cater to overflows. Take a look at this example:

DATA: p TYPE p(12) DECIMALS 4,
      f TYPE f.

...

TRY.
    p = f.
  CATCH cx_sy_conversion_overflow.
    WRITE:/ 'Overflow'.
ENDTRY.

WRITE: f,p.

Note that calculations involving type p fields are slower than those using type f and type i, so take care when working on these type of fields.
