Java - min float value
4 points
In Java, min float number value can be achieved using -Float.MAX_VALUE what is equal to -3.4028235e+38f.
Practical example:
xxxxxxxxxx1
package example;2
3
public class Program {4
5
public static void main(String[] args) {6
7
System.out.println(-Float.MAX_VALUE); // -3.4028235e+38f or in hex: -0x1.fffffeP+127f8
}9
}Output:
xxxxxxxxxx1
-3.4028235e+38fWarning: do not confuse
Float.MIN_VALUEwith float minimal value - it returns min positive float value.
Sometimes it is necessary to know minimal positive float value. To get its we can use Float.MIN_VALUE.

// Min positive float value:8
//9
System.out.println(Float.MIN_VALUE); // 1.4e-45f or in hex: 0x0.000002P-126f10
