JavaScript Tutorial » Number Data Type » Introdunction   5. 1. 12. Number.MAX_VALUE and Number.MIN_VALUE define the outer bounds of the Number value set All numbers must fall between Number.MAX_VALUE and Number.MIN_VALUE. When a calculation results in a number greater than Number.MAX_VALUE, it is assigned a value of Number.POSITIVE_INFINITY. When a calculation results in a number less than Number.MIN_VALUE, it is assigned a value of Number.NEGATIVE_ INFINITY. If a calculation returns an infinite value, the result cannot be used in any further calculations. There is a special value for infinity named Infinity. Number.POSITIVE_ INFINITY has a value of Infinity. Number.NEGATIVE_INFINITY has a value of -Infinity. A method can be used to determine if a number is finite. var iResult = iNum* some_really_large_number; if (isFinite(iResult)) {     alert("Number is finite."); } else {     alert("Number is infinite."); } 5. 1. Introdunction 5. 1. 1.  Numbers 5. 1. 2.  Number() Object 5. 1. 3.  Variables are loosely typed. 5. 1. 4.  Built-in Values 5. 1. 5.  Special Numerical Values 5. 1. 6.  Primitive and Reference Values 5. 1. 7.  Primitive Types 5. 1. 8.  The Undefined Type 5. 1. 9.  The Null Type 5. 1. 10.  The Boolean Type 5. 1. 11.  The Number Type 5. 1. 12.  Number.MAX_VALUE and Number.MIN_VALUE define the outer bounds of the Number value set 5. 1. 13.  NaN stands for Not a Number 5. 1. 14.  JavaScript primitive values, Booleans, numbers, and strings, are pseudo-objects 5. 1. 15.  Reference Types
