I8 extension type
An 8-bit signed integer primitive.
This provides a zero-cost abstraction for 8-bit signed math, automatically wrapping on overflow and providing C++-style boundaries.

Methods
-
abs(
) → int -
Returns the absolute value of this integer.
inherited
-
addChecked(
I8 other) → I8 - Adds another I8 to this, throwing a StateError on overflow or underflow.
-
ceil(
) → int -
Returns
this.inherited -
ceilToDouble(
) → double -
Returns
this.toDouble().inherited -
clamp(
num lowerLimit, num upperLimit) → num -
Returns this num clamped to be in the range
lowerLimit-upperLimit.inherited -
compareTo(
num other) → int -
Compares this to
other.inherited -
floor(
) → int -
Returns
this.inherited -
floorToDouble(
) → double -
Returns
this.toDouble().inherited -
gcd(
int other) → int -
Returns the greatest common divisor of this integer and
other.inherited -
modInverse(
int modulus) → int -
Returns the modular multiplicative inverse of this integer
modulo
modulus.inherited -
modPow(
int exponent, int modulus) → int -
Returns this integer to the power of
exponentmodulomodulus.inherited -
mulChecked(
I8 other) → I8 - Multiplies this by another I8, throwing a StateError on overflow or underflow.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
remainder(
num other) → num -
The remainder of the truncating division of
thisbyother.inherited -
round(
) → int -
Returns
this.inherited -
roundToDouble(
) → double -
Returns
this.toDouble().inherited -
subChecked(
I8 other) → I8 - Subtracts another I8 from this, throwing a StateError on overflow or underflow.
-
toDouble(
) → double -
This number as a double.
inherited
-
toInt(
) → int -
Truncates this num to an integer and returns the result as an int.
inherited
-
toRadixString(
int radix) → String -
Converts this int to a string representation in the given
radix.inherited -
toSigned(
int width) → int -
Returns the least significant
widthbits of this integer, extending the highest retained bit to the sign. This is the same as truncating the value to fit inwidthbits using an signed 2-s complement representation. The returned value has the same bit value in all positions higher thanwidth.inherited -
toString(
) → String -
Returns a string representation of this integer.
inherited
-
toStringAsExponential(
[int? fractionDigits]) → String -
An exponential string-representation of this number.
inherited
-
toStringAsFixed(
int fractionDigits) → String -
A decimal-point string-representation of this number.
inherited
-
toStringAsPrecision(
int precision) → String -
A string representation with
precisionsignificant digits.inherited -
toUnsigned(
int width) → int -
Returns the least significant
widthbits of this integer as a non-negative number (i.e. unsigned representation). The returned value has zeros in all bit positions higher thanwidth.inherited -
truncate(
) → int -
Returns
this.inherited -
truncateToDouble(
) → double -
Returns
this.toDouble().inherited
