This number is 447,000,000 . Or 4.47 × 10 ^ 8 . It is more convenient to write on the computer this way.
Here is the answer WolframAlpha
Answer 1, authority 100%
Normal demolition of digits in a number. When is written 4.47 10 ^ 8, the floating point is assumed to be shifted by 8 digits forward – in this case this will be the number 447 with 6 leading zeros, i.e. e. 447.000.000 . In programming, E-values can be used, and e cannot be written by itself , but E – it is possible (but not everywhere and not always, this will be noted below), since the penultimate may be mistaken for Euler’s number . If you need to write a huge number in abbreviated form, the 4.47 E8 style can be used (an alternative option for production and small-font printing is 4.47 × E8), so that the number is read more unloaded and the digits are indicated more separately (you cannot put spaces between arithmetic signs – in otherwise, it is a mathematical condition, not a number).
3.52E3 is fine for writing without indices, but reading the bit offset will be more difficult. 3.52 10 ^ 8 is a condition, since requires an index and there is no mantissa (the latter exists only for the operator, and this is an extended factor). ’10’ is the process of standard (main) operational multiplication, the number after ^ is an indicator of the drift of the digits, so it does not need to be made small if it is necessary to write documents in this form (observing the superscript position), in some cases, it is advisable to use the scale in the region 100 – 120%, not the standard 58%. Using a small scale for the key elements of the condition, the visual quality of digital information decreases – you have to peer (it may not be necessary, but the fact remains – you don’t need to “hide” the conditions in small print, you could even “bury” – reduce the scale of individual elements of the condition. unacceptable, especially on a computer) to notice a “surprise”, which is very harmful even on a paper resource.
If the multiplication process performs special operations, then in such cases the use of spaces may be redundant, because in addition to multiplying numbers, the multiplier can be a connecting link for huge and small numbers, chemical elements, etc. and the like, which cannot be written as a decimal fraction of ordinary numbers or cannot be written in the final result. This may not apply to the entry with ’10 ^ y’, since any value in the expression acts as a multiplier, and ‘^ y’ is the superscript degree, i.e. is a numeric condition. But removing the spaces around the multiplier and writing it differently will be a mistake, since operator is missing. The excerpt from the notation ’10’ itself is a multiplier operator + a number, not the first + second operator. Here is the main reason why it is impossible with a 10. If there are no special values after the numeric operator, i.e. non-numeric, but systemic, then this writing option cannot be justified – if there is a system value, then such a value should be suitable for certain tasks with a numerical or practical reduction of numbers (for certain actions, for example, 1.35f8, where f is any an equation created for practical special problems, which displays real numbers as a result of specific practical experiments, 8 is a value that is substituted as a variable to the operator f and coincides with the numbers when conditions are successively changed in the most convenient way, if this problem is of paramount importance, then such values can be used with no spaces). Briefly, for similar arithmetic operations, but for different purposes, you can also do with pluses, minuses and divisors, if there is an urgent need to create new or simplify existing methods of writing data while maintaining accuracy in practice and can be an applicable numerical condition for certain arithmetic purposes.
Outcome: The officially approved form of an exponential recording is recommended to write with a space and scale of the fest 58% and a displacement of 33% (if the scale change and displacement is allowed by other parties at 100 – 120%, then 100% can be installed – this is the most The optimal version of the recording of the supreme values, the optimal displacement is ≈ 50%). On the computer you can use 3,74e + 2, 4.58e-1, 6.73 · E-5, E-11, if the last two formats are supported, it is better to abandon the forums from E-abbreviations for known reasons, and style 3, 65 · E-5 or 5,67E4 can be completely clear, exceptions can be only Official public segments – there only with ‘· 10 ^ x ‘, and Instead of ^ x, only the degree of is used.
In short, e is a supervisor for a decimal antilogarithm, which is often labeled as Antilog or Antilg. For example, 7,947Antilg-4 will be equal as 7,947 E-4. In practice, it is much more practical and more convenient than to hide the “dozen” with a sudden date of a degree once again. This can be called an “exponential” logarithmic view of the number as an alternative to a less convenient “exponential” classic. Only instead of “antilg”, “E” either immediately goes the second number with the pass (if the number is positive) is either without it (on ten-segment scientific calculators, such as “Citizen CT-207T”).
When I saw such a rule. Just when reading the letter E (which went from the word of the exhibitor) reads how to “multiply ten to degree” and everything will be clear.
speaking by simple
100000000 = 1e + 08,
1000000000 = 1e + 09
