Number constants
suggest changeThe Number
constructor has some built in constants that can be useful
Number.MAX_VALUE; // 1.7976931348623157e+308Number.MAX_SAFE_INTEGER; // 9007199254740991Number.MIN_VALUE; // 5e-324Number.MIN_SAFE_INTEGER; // -9007199254740991Number.EPSILON; // 0.0000000000000002220446049250313Number.POSITIVE_INFINITY; // InfinityNumber.NEGATIVE_INFINITY; // -InfinityNumber.NaN; // NaN
In many cases the various operators in Javascript will break with values outside the range of (Number.MIN_SAFE_INTEGER
, Number.MAX_SAFE_INTEGER
)
Note that Number.EPSILON
represents the different between one and the smallest Number
greater than one, and thus the smallest possible difference between two different Number
values. One reason to use this is due to the nature of how numbers are stored by JavaScript see Check the equality of two numbers
