// Global object: methods
Number.EPSILON // The smallest interval between two representable numbers.
Number.MAX_SAFE_INTEGER // The maximum safe integer in JavaScript (253 - 1).
Number.MAX_VALUE // The largest positive representable number.
Number.MIN_SAFE_INTEGER // The minimum safe integer in JavaScript (-(253 - 1)).
Number.MIN_VALUE // The smallest positive representable number—that is, the positive number closest to zero (without actually being zero).
Number.NaN // Special "Not a Number" value.
Number.NEGATIVE_INFINITY // Special value representing negative infinity. Returned on overflow.
Number.POSITIVE_INFINITY // Special value representing infinity. Returned on overflow.
Number.isFinite(value) // Determine whether the passed value is a finite number, returns a boolean.
Number.isInteger(value) // Determine whether the passed value is an integer, returns a boolean.
Number.isNaN(value) // Determine whether the passed value is NaN, returns a boolean.
Number.isSafeInteger() // Determine whether the passed value is a safe integer (number between -(253 - 1) and 253 - 1), returns a boolean.
Number.parseFloat() // Parses a string argument and returns a floating point number, this is the same as the global parseFloat() function.
Number.parseInt() // Parses a string argument and returns an integer of the specified radix, this is the same as the global parseInt() function.
// Methods
number.toExponential(fractionDigits) // Returns a string representing the number in exponential notation.
number.toFixed(digits) // Returns a string representing the number in fixed-point notation.
number.toLocaleString(locales, options) // Returns a string with a language-sensitive representation of this number.
number.toPrecision(precision) // Returns a string representing the number to a specified precision in fixed-point or exponential notation.
number.toString(radix) // Returns a string representing the specified number value.
number.valueOf(radix) // Returns a string representing the specified number value.
