Find out the Maximum value and Minimum value a float type can have

Type	Field	Summary
static float	MAX_VALUE	Largest positive finite value of type float.
static float	MIN_VALUE	Smallest positive nonzero value of type float.
static int	MAX_EXPONENT	Maximum exponent a finite float variable may have.
static int	MIN_EXPONENT	Minimum exponent a normalized float variable may have.
static float	MIN_NORMAL	Smallest positive normal value of type float.


public class Main {
  public static void main(String[] args) {
    System.out.println("MAX_VALUE:"+Float.MAX_VALUE);
    System.out.println("MIN_VALUE:"+Float.MIN_VALUE);
    System.out.println("MAX_EXPONENT:"+Float.MAX_EXPONENT);
    System.out.println("MIN_EXPONENT:"+Float.MIN_EXPONENT);
    System.out.println("MIN_NORMAL:"+Float.MIN_NORMAL);
  }
}

The output:


MAX_VALUE:3.4028235E38
MIN_VALUE:1.4E-45
MAX_EXPONENT:127
MIN_EXPONENT:-126
MIN_NORMAL:1.17549435E-38

Type	Field	Summary
static float	NaN	Not-a-Number (NaN) value of type float.
static float	NEGATIVE_INFINITY	Negative infinity of type float.
static float	POSITIVE_INFINITY	Positive infinity of type float.
static int	SIZE	The number of bits used to represent a float value.
static Class	TYPE	The Class instance representing the primitive type float.


public class Main {
  public static void main(String[] args) {
    System.out.println("NaN:"+Float.NaN);
    System.out.println("NEGATIVE_INFINITY:"+Float.NEGATIVE_INFINITY);
    System.out.println("POSITIVE_INFINITY:"+Float.POSITIVE_INFINITY);
    System.out.println("SIZE:"+Float.SIZE);
  }
}

The output:


NaN:NaN
NEGATIVE_INFINITY:-Infinity
POSITIVE_INFINITY:Infinity
SIZE:32
