Definition of fractional in English: fractionaladjective ˈfrakʃ(ə)n(ə)lˈfrækʃ(ə)n(ə)l 1Relating to or expressed as a fraction, especially a fraction less than one. （尤指小于1的）分数（或小数）的 the fractional variance in mass density per unit Example sentencesExamples - This number could be either integral or fractional.
- He also worked on asymptotic analysis, fractional integration and singular partial differential equations.
- Much of Burnside's work on hydrodynamics involved the use of complex variable and in papers of 1891 and 1892 he considered the group of linear fractional transformations of a complex variable.
- The computer programs implement basic mathematical principles such as basic geometry and fractional math.
