Normalized notation

Any accustomed amount can be accounting in the anatomy of a×10b in abounding ways; for example, 350 can be accounting as 3.5×102 or 35×101 or 350×100.

In normalized accurate notation, the backer b is alleged so that the complete amount of a charcoal at atomic one but beneath than ten (1 ≤ |a| < 10). Following these rules, 350 would consistently be accounting as 3.5×102. This anatomy allows simple allegory of two numbers of the aforementioned assurance in a, as the backer b gives the number's adjustment of magnitude. In normalized notation, the backer b is abrogating for a amount with complete amount amid 0 and 1 (e.g., abrogating one bisected is accounting as −5×10−1). The 10 and backer are usually bare if the backer is 0. Note that 0 cannot be accounting in normalized accurate characters back it cannot be bidding as a×10b for any non-zero a.

Normalized accurate anatomy is the archetypal anatomy of announcement of ample numbers for abounding fields, except during average calculations or if an unnormalised form, such as engineering notation, is desired. Normalized accurate characters is generally alleged exponential notation—although the closing appellation is added accepted and aswell applies if a is not belted to the ambit 1 to 10 (as in engineering characters for instance) and to bases added than 10 (as in 315× 220).
