How do I divide so I get a decimal value

Question

I want to know how to get remainder and quotient in single value in Java   Example         3 2 I should get value as 1 5    If I use the   operator I get only the quotient  If I user the   operator I get only the remainder  How do I get both at a time in the same variable

int a   3  int b   2  float c     float a  b

User · Answer

quotient   3   2  remainder   3   2      now you have them both

If you initialize both the parameters as float  you will sure get actual divided value  For example   float RoomWidth  TileWidth  NumTiles  RoomWidth   142  TileWidth   8  NumTiles   RoomWidth TileWidth       Ans 17 75

Don t worry about it  In your code  just do the separate   and   operations as you mention  even though it might seem like it s inefficient  Let the JIT compiler worry about combining these operations to get both quotient and remainder in a single machine instruction  as far as I recall  it generally does

Check this out  http   download oracle com javase 1 5 0 docs api java math BigDecimal html divideAndRemainder 28java math BigDecimal 29  You just need to wrap your int or long variable in a BigDecimal object  then invoke the divideAndRemainder method on it  The returned array will contain the quotient and the remainder  in that order

Please Convert your input in double and divide

In your example  Java is performing integer arithmetic  rounding off the result of the division   Based on your question  you would like to perform floating-point arithmetic   To do so  at least one of your terms must be specified as  or converted to  floating-point   Specifying floating point   3 0 2 3 0 2 0 3 2 0   Converting to floating point   int a   2  int b   3  float q     float a  b    or  double q     double a  b     See Java Traps  double and Java Floating-Point Number Intricacies for discussions on float and double

You can do like   int a   3  int b   2  int quotient   a   b  int remainder   a   b       To get quotient in real numbers   System out println  double  a   b        To get quotient in integer numbers   System out println  Quotient      quotient   System out println  Remainder      remainder        To get quotient in real number such that one number after decimal   System out println a   b         a   b   10   b        Note  In the last method it will not round the number up after the decimal

I mean it s quite simple  Set it as a double  So lets say  double answer   3 0 2 0  System out print answer
