Java Language Java Floating Point Operations OverFlow and UnderFlow
Example
Float data type
The float data type is a single-precision 32-bit IEEE 754 floating point.
Float overflow
Maximum possible value is 3.4028235e+38 , When it exceeds this value it produces Infinity
float f = 3.4e38f;
float result = f*2;
System.out.println(result); //Infinity
Float UnderFlow
Minimum value is 1.4e-45f, when is goes below this value it produces 0.0
float f = 1e-45f;
float result = f/1000;
System.out.println(result);
double data type
The double data type is a double-precision 64-bit IEEE 754 floating point.
Double OverFlow
Maximum possible value is 1.7976931348623157e+308 , When it exceeds this value it produces Infinity
double d = 1e308;
double result=d*2;
System.out.println(result); //Infinity
Double UnderFlow
Minimum value is 4.9e-324, when is goes below this value it produces 0.0
double d = 4.8e-323;
double result = d/1000;
System.out.println(result); //0.0
