# num class

An integer or floating-point number.

It is a compile-time error for any type other than int or double to attempt to extend or implement num.

Implements
  - Comparable<num>
Implemented by
  - double
  - int

## Constructors

num()

## Properties

hashCode → int
  Returns a hash code for a numerical value. [...]
  read-only
isFinite → bool
  True if the number is finite; otherwise, false. [...]
  read-only
isInfinite → bool
  True if the number is positive infinity or negative infinity; otherwise, false.
  read-only
isNaN → bool
  True if the number is the double Not-a-Number value; otherwise, false.
  read-only
isNegative → bool
  True if the number is negative; otherwise, false. [...]
  read-only
sign → num
  Returns minus one, zero or plus one depending on the sign and numerical value of the number. [...]
  read-only
runtimeType → Type
  A representation of the runtime type of the object.
  read-only, inherited

## Methods

abs() → num
  Returns the absolute value of this num.
ceil() → int
  Returns the least integer no smaller than `this`. [...]
ceilToDouble() → double
  Returns the least double integer value no smaller than `this`. [...]
clamp(num lowerLimit, num upperLimit) → num
  Returns this num clamped to be in the range `lowerLimit`-`upperLimit`. [...]
compareTo(num other) → int
  Compares this to `other`. [...]
floor() → int
  Returns the greatest integer no greater than `this`. [...]
floorToDouble() → double
  Returns the greatest double integer value no greater than `this`. [...]
remainder(num other) → num
  Returns the remainder of the truncating division of `this` by `other`. [...]
round() → int
  Returns the integer closest to `this`. [...]
roundToDouble() → double
  Returns the double integer value closest to `this`. [...]
toDouble() → double
  Return this num as a double. [...]
toInt() → int
  Truncates this num to an integer and returns the result as an int.
toString() → String
  Returns the shortest string that correctly represent the input number. [...]
toStringAsExponential([int fractionDigits ]) → String
  Returns an exponential string-representation of `this`. [...]
toStringAsFixed(int fractionDigits) → String
  Returns a decimal-point string-representation of `this`. [...]
toStringAsPrecision(int precision) → String
  Converts `this` to a double and returns a string representation with exactly `precision` significant digits. [...]
truncate() → int
  Returns the integer obtained by discarding any fractional digits from `this`. [...]
truncateToDouble() → double
  Returns the double integer value obtained by discarding any fractional digits from the double value of `this`. [...]
noSuchMethod(Invocation invocation) → dynamic
  Invoked when a non-existent method or property is accessed. [...]
