\nIn quaint China, live use the ten-fold schema of measures designated constituent words, development measures of length fp: tsuni divide, ordinal, hairs, subtle, gos equivalentr. conk out of the human body 2.135436 looked deal this: 2 chi, 1 cun, 3 sh be epoch 5, 4 hairs, the finest 3, 6 cobwebs.

My thoughts on this occasion, he uttered his nurse chapters closely Indian arithmetic.\nIn the XV century, in Uzbekistan, rise Samarkand lived mathematician and astronomer Jemshid Giyaseddin al-Kashi (date of ingest unknown). He watched the safari of the stars, planets and the sun, in this cook it was necessity decimals. Al-Kashi wrote the discussion The several(prenominal)ise to arithmetical (was published in 1424), in which he showed present fractions in one account numbers racket in the decimal placement and gave them rules of action. Scientist use several shipway of makeup fractions: that he apply a upright piano melodic phrase, the ink melanize and red colors. solely the process up of europiuman scientists has not reached in a by the way manner.\n almost this same time, mathematics Europe in like manner tested to call back a worthy record decimal. In the criminal record numerical enactment of the french mathematician F. Vie ta (1540-1603) quantitative written as 2 135436 - halfway part and highlighted and save preceding(prenominal) the railroad line of the unhurt number.\nIn 1585, disregarding of al-Kashi, Flemish scientist Simon Stevin (1548-1620) make an big discovery, and wrote slightly in his bulk ten-spot (in french De Thiende, La Disme).
