ERROR : possible loss of precision

Hi all,

I tried to initialize a decimal value as shown below

Code:

---

float a = 30.9;

---

It gives compiler error "possible loss of precision"
But when I did typecasting as shown below it worked

Code:

---

float a = (float)30.9;

---

Seems like it is interpreting 30.9 as double.

In C and C++ it is okay to declare float variables as above.
How is this different in Java? Could anyone please help.

The literal 30.9 is indeed a double. To specify it as a float, add an F to the end:

Code:

---

float a = 30.9F
