Constants

const Precision = 128

note: all coefficients for which Polyval is used would need to be updated if this precision changes

Functions

func Parse

func Parse(coefs []string) []*big.Int

Parse a slice of strings (representing integers in decimal) Convention: this function is to be applied to strings representing Q.128 fixed-point numbers, and thus returns numbers in binary Q.128 representation

func Polyval

func Polyval(p []*big.Int, x *big.Int) *big.Int

polyval evaluates a polynomial given by coefficients `p` in Q.128 format at point `x` in Q.128 format. Output is in Q.128. Coefficients should be ordered from the highest order coefficient to the lowest.
