Most of the time, when we measure and measure does not require precise and instead will deliberately blur it, and produced some fuzzy number and fuzzy classifier
Many times, when we do not need to measure and measure it accurately, but it will also deliberately to blur it, so he produced some of Fuzzy Numbers and Fuzzy quantifiers
Most of the time, we measure and measure does not need to be exact, but it will also try to obscure it and then some fuzzy numbers and fuzzy quantifiers
