Other library functions:

Dissonance functions for musical interval x>1:
diss(c,x) gives the dissonance value of x for accuracy c>0.
diss.f(c,x) gives the ratio n:m in the form m+n/1000, i.e.
            n:m is the best rational approximation for x.
            Example: diss.f(5,3.141592653589793)=7.022  (22:7)

bestval(a,b) finds the `nicest' number in the closed interval.
             This function can be used for finding suitable scale
             notations. For example, sucros may produce good
             XSCALE and YSCALE specifications for plotting schemes.
             Example: bestval(1.27,7.34)=5
