isNaN → bool?
True if the number is the double Not-a-Number value; otherwise, false.
no setter
isNegative → bool?
True if the number is negative; otherwise, false.
no setter
sign → num?
Returns minus one, zero or plus one depending on the sign and numerical value of the number.
no setter

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.
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. */
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.
