decimal numeration
2.The positive integer by which the weight of the digit place is multiplied to obtain the weight of the digit place with the next higher weight, for example, in the decimal numeration system the radix of each digit place is 10, in a biquinary code the radix of each fives position is 2.
7.The fixed radix numeration system that uses the decimal digits and the radix 10 and in which the lowest integral weight is 1.
8.For instance, as E the Roman system of numeration, the number thirty would have to be written as X: while as per the decimal system it would 30, further the number thirty three would be XXXIII as per the Roman system, would be 33 as per the decimal system.
9.A term sometimes applied to a numeric representation in the binary numeration system(as contrasted, possibly, to binary coded decimal or some other represen tation using0-bits and1-bits).
10.a radix numeration system in which the location of the decimal point is indicated by an exponent of the radix; the floating-point representation of 0.0012 is 0.l2-2 where -2 is the exponent.
