Math.round -> round to nearest value. eg- 5.3 to 5.0 and 5.7 to 6.0 Math.floor -> round to nearest lower limit. eg- 5.6 to 5.0 Math.ceil -> round to nearest upper limit. eg- 5.2 to 6.0

To understand what you need more, Can you share your try? Edit: double a=3.45; a=a-a%1; //floor a=(a-a%1)+1; //ceil

"Without using any method" so you can't use Math functions (type casting) is good way, +1 if dec%1>=0.5 then solve negative sign for -2.55 -> -3.0
