In some cases we need to convert float values. Here’s a simple example.

DATA :
lv_in TYPE atflv VALUE ‚2.1000000000000000E+01‘,
lv_out     TYPE cha_class_view–sollwert.

CLEAR : lv_out.
CALL FUNCTION ‚QSS0_FLTP_TO_CHAR_CONVERSION‘
EXPORTING
i_number_of_digits   = 2
i_fltp_value         = lv_in
i_screen_fieldlength = 16
IMPORTING
e_char_field         = lv_out.
WRITE : /  lv_out.

output :  21.00
