This is an updated version of SigmoidNumbers for Posits, Valids and Unum II Numbers for Julia by Mohammad Hizzani
Based on the Sigmoid Numbers Invented by John Gustafson
ML Applications & Implementation by Isaac Yonemoto
Two types of Sigmoid Numbers
-
Universal Sigmoid Numbers
-
Estimated Sigmoid Numbers (Posits)
In order to add SigmoidNumbers simply from a Julia REPL
julia> ] add SigmoidNumbersTo use it
julia> using SigmoidNumbers
julia> P1 = Posit{16,0}; #16 is number of bits, 0 is ES
julia> a = P1(0)
Posit{16,0}(0x0000)
