Here's the Python solution. ---------- # -*- coding: utf-8 -*- # Python

For example, the last item returned from # Range(0,18,0.3) is 17.7 not 18. A remedy is to turn iStep into a # fraction and do exact arithmetics, and possibly convert the result # back to decimal. A lesser workaround is to split the interval as to # do multiple smaller range and join them together. def Range(iMin, iMax=None, iStep=None): if (iMax==None and iStep==None): return Range(1,iMin) if iStep==None: return Range(iMin,iMax,1) if iMin <= iMax and iStep > 0: if (isinstance(iStep,int) or isinstance(iStep,long)): return range( iMix, iMax, iStep) else: result=[];temp=iStep while iMin <= iMax: result.append(iMin) iMin += iStep return result # test print Range(0, 18, 0.3) -- http://mail.python.org/mailman/listinfo/python-list
