# Functions
ExpNeg accepts x in Q.128 format and computes e^-x.
The natural log of Q.128 x.
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.
polyval evaluates a polynomial given by coefficients `p` in Q.128 format at point `x` in Q.128 format.
# Constants
note: all coefficients for which Polyval is used would need to be updated if this precision changes.
