Types ¶
type Number ¶
type Number struct {
// contains filtered or unexported fields
}
Number represents a rational number.
func FromRational ¶
FromRational creates a new rational number from a big.Rat.
func (*Number) Cmp ¶
Cmp compares two rational numbers: -1 if r < other, 0 if r == other, 1 if r > other.
func (*Number) Constructive ¶
func (r *Number) Constructive() constructive.Real
Constructive converts the rational number to a constructive real.
func (*Number) ShiftLeft ¶
ShiftLeft shifts the rational number left by n bits (multiplies by 2^n). Supports signed shifts: negative n shifts right.
func (*Number) ShiftRight ¶
ShiftRight shifts the rational number right by n bits (divides by 2^n). Supports signed shifts: negative n shifts left.
func (*Number) Sign ¶
Sign returns the sign of the rational number: -1 for negative, 0 for zero, 1 for positive.
