Round number in ABAP

Use ceil( ) or floor( ) to round decimal to integer, respectively to upper or lower integer value.

  DATA(lv_upper_value) = ceil( '0.333' ). " ==> 1

  DATA(lv_lower_value) = floor( '1.66' ). " ==> 1

Use the round( ) method to have more possibilities :

  DATA : lv_percentage TYPE numc3.
  " [...]

  " In this case, the percentage calc is round to lower integer value :
  lv_percentage =  = CONV #( round( val  = lv_num / lv_total * 100
                                    dec  = 0
                                    mode = cl_abap_math=>round_down )  ).

You can specify in wich mode you want to round number with :

CL_ABAP_MATH=>ROUND_HALF_UP	|	Round away from zero if value is exactly half
CL_ABAP_MATH=>ROUND_HALF_DOWN	|	Round to zero if value is exactly half
CL_ABAP_MATH=>ROUND_HALF_EVEN	|	Round so last digit is an even no. if value is exactly half
CL_ABAP_MATH=>ROUND_UP		|	Round away from zero
CL_ABAP_MATH=>ROUND_DOWN	|	Round to Zero
CL_ABAP_MATH=>ROUND_CEILING	|	Round to Positive Infinity
CL_ABAP_MATH=>ROUND_FLOOR	|	Round to Negative Infinity
