Methods
-
compareTo(
F other) → int -
Lexicographic comparison of field elements.
override
-
conditionalSelect(
F a, F b, bool choice) → F -
Conditional selection: returns
bif choice is true,aotherwise. -
double(
) → F -
Doubles the element.
override
-
getLower32(
) → int - Returns the lowest 32 bits of the field element.
-
invert(
) → F? -
Computes the multiplicative inverse.
override
-
isOdd(
) → bool - Returns true if the element is odd (least significant bit = 1)
-
isZero(
) → bool -
Returns true if the element is zero.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
powByTMinus1Over2(
) → F - Computes (self)^((t - 1)/2), used in curve-specific operations.
-
sqrt(
) → FieldSqrtResult< F> -
Computes the square root of the element.
override
-
square(
) → F -
Squares the element.
override
-
sRatio(
F a, F b) → FieldSqrtResult< F> -
toBits(
) → List< bool> - Returns the field element as a list of bits (little-endian per limb).
-
toBytes(
) → List< int> -
Serializes the field element to bytes.
override
-
toString(
) → String -
A string representation of this object.
