When we write a display division, we can draw a “bridge” over the partof dividend which is taken in count for the first step of calculation. Thexlop package allow to draw this symbol thanks to the boolean parameterdividendbridge (default value isfalse).1 2 5 45 42 4 003 04 1.8 source\opdiv[dividendbridge]{1254}{30}3.4.3 Non Integer Numbers and Negative NumbersThe shiftdecimalsep parameter governs non integer operands aspect/Its default value is both which indicates that decimal separator is shiftedin order to obtain integer divisor and integer dividend. The valuedivisorindicates that there is the shifting that allows an integer divisor. The valuenone indicates that there isn’t any shifting.source\opdiv[shiftdecimalsep=both]{3.456}{25.6}\quad\opdiv[shiftdecimalsep=divisor]{3.456}{25.6}\quad\opdiv[shiftdecimalsep=none]{3.456}{25.6}3 4 5 63 4 5 6 08 9 6 0 01 2 8 0 0 002 5 6 0 00.1 3 5 3 4.5 68 9 61 2 8 002 5 60.1 3 53.4 5 68 9 61 2 8 002 5.60.1 3 5Parameter strikedecimalsepsymbol gives the symbol used to showthe old place of decimal separator when this one is shifted. The defaultvalue is empty, that is, there isn’t any symbol. This explain why you don’tsee anything on previous examples.source\opset{strikedecimalsepsymbol={\rlap{,}\rule[­1pt]{3pt}{0.4pt}}}\opdiv[shiftdecimalsep=both]{3.456}{25.6}\quad\opdiv[shiftdecimalsep=divisor]{3.456}{25.6}\quad\opdiv[shiftdecimalsep=none]{3.456}{25.6}3 , 4 5 63 4 5 6 08 9 6 0 01 2 8 0 0 002 5 , 6 0 00.1 3 5 3 , 4.5 68 9 61 2 8 002 5 , 60.1 3 53.4 5 68 9 61 2 8 002 5.60.1 3 5When there is a non empty symbol for the striked decimal separator, itis possible to have non-significant zeros in operands.21
