- sign → num
-
Returns minus one, zero or plus one depending on the sign and
numerical value of the number.

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
thisbyother. -
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
thisto a double and returns a string representation with exactlyprecisionsignificant 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.
