Converts this BigInteger to a float .

Usage

From source file:Main.java

public static void main(String[] args) {

    // assign values to bi1, bi2
    BigInteger bi1 = new BigInteger("123");
    BigInteger bi2 = new BigInteger("-123");

    // assign float values of bi1, bi2 to f1, f2
    Float f1 = bi1.floatValue();
    Float f2 = bi2.floatValue();//  ww  w.ja  va2 s .  c o  m

    // print f1, f2 values
    System.out.println(f1);
    System.out.println(f2);
}
