How can I convert integer into float in Java

Question

I have two integers x and y  I need to calculate x y and as outcome I would like to get float  For example as an outcome of 3 2 I would like to have 1 5  I thought that easiest  or the only  way to do it is to convert x and y into float type  Unfortunately  I cannot find an easy way to do it  Could you please help me with that

Here is how you can do it    public static void main String   args           TODO Auto-generated method stub     int x   3      int y   2      Float fX   new Float x       float res   fX floatValue   y      System out println  res     res       See you

Sameer   float l   new Float x y    will not work  as it will compute integer division of x and y first  then construct a float from it   float result    float  x    float  y    Is semantically the best candidate

You just need to transfer the first value to float  before it gets involved in further computations   float z   x   1 0   y

You shouldn t use float unless you have to  In 99  of cases  double is a better choice   int x   1111111111  int y   10000  float f    float  x   y  double d    double  x   y  System out println  f    f   System out println  d    d     prints  f  111111 12 d  111111 1111   Following  Matt s comment   float has very little precision  6-7 digits  and shows significant rounding error fairly easily  double has another 9 digits of accuracy  The cost of using double instead of float is notional in 99  of cases however the cost of a subtle bug due to rounding error is much higher   For this reason  many developers recommend not using floating point at all and strongly recommend BigDecimal     However I find that double can be used in most cases provided sensible rounding is used   In this case  int x has 32-bit precision whereas float has a 24-bit precision  even dividing by 1 could have a rounding error  double on the other hand has 53-bit of precision which is more than enough to get a reasonably accurate result

You just need to cast at least one of the operands to a float   float z    float  x   y    or  float z   x    float  y    or  unnecessary   float z    float  x    float  y
