Struct wigner_symbols::SignedSqrt
[−]
[src]
pub struct SignedSqrt(pub Rational);
Signed square root of a rational number
This represents a mathematical expression of the form s √(n / d)
where
s
is a sign (-1
,0
, or+1
),n
is a nonnegative numerator, andd
is a positive denominator.
Internally, it is represented by the rational number s × n / d
.
This can be converted to a floating-point number via f64::from(…)
.
Defaults to zero.
Methods
impl SignedSqrt
[src]
fn new(c: Integer, r: Rational) -> Self
[src]
Construct a SignedSqrt

fn signed_sq(self) -> Rational
[src]
Returns the square of the expression, but with the sign adjusted to match the sign of the original expression.
