### Why is the size of a decimal number not necessarily determined by the number of decimal places notated?

Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to… Read More

### What are the rules for putting integers in order from least to greatest?

First, separate the negative and positive integers (put them into two separate groups). If there is a zero, you can put it in its own group - or put it into the same group with the positive integers. Negative integers come first, then zero, then positive integers. For positive integers: An integer with less digits comes before an integer with more digits. For integers with the same number of digits, look at the first digit… Read More

The digits of a value which can be used with accuracy with other values. ie- you have two measurements, 13.6mg and 15.716mg. The most digits you can use are 3, because 13.6 has an accuracy of 3 digits. If you used 5 digits, accuracy would be limited because you do not know/have the 4th and 5th digits of the first value. When a a significant digit is followed by an exact 5, round to the… Read More

### Why is it important to use significant digits to round the answer?

Because the extra digits are just clutter suggesting a spurious level of accuracy.

### What is the accurate version of pi?

pi is an irrational number and one characteristic of irrational numbers is that their decimal representation is neither terminating nor recurrent. This is also true for any other base for counting (other than pi itself). Also, pi is a transcendental number and so cannot be represented as a sum of algebraic operation on integers. Although the value of pi has been calculated to an accuracy of over a trillion digits, only 40 digits are required… Read More

### What kind of numbers are decimals with a repeating pattern of digits?

either irrational numbers, integers, integers, rational numbers, or whole numbers

### How do you round off 12.4263?

### How many 1-digit integers are there such that product of their two digit is 24?

None. By definition, 1-digit integers cannot have two digits!

### How many significant digits does 9.081.000 have?

Assuming the full stops are thousand separators, the answer is 4 significant digits. However, integers ending in zero are ambiguous.

### What are the last two digits in the sum of factorials of the first 100 positive integers?

There are 125 of them.

### A 2 digit number that is the product of 2 consecutive integers and the sum of its digits is greater than the product of the digits both digits are even?

The 2-digit number must be 20, because it is the only 2-digit number whose sum of its two even digits, 2 + 0 = 2, is greater than the product of its two even digits, 2 x 0 = 0. Moreover, 20 is a product of the two consecutive integers 4 and 5.

### How many significant digits are in 2300?

Integers with trailing 0s are ambiguous. There are at least two significant digits but, if the number is known to be accurate to the nearest integer, there are 4

One. Although integers ending in 0 are ambiguous. If the number is known to be accurate to the nearest ten, for example, then there are 3 significant digits.

### How many positive integers have exactly three digits?

Every number from 100 to 999 inclusive !

### How many significant digits does 4.450 have?

Five. Zeros that are after the decimal and are after nonzero integers are always significant.

### What is thesmallest 3digit number with unique digits?

### What is meant by data precision in computer?

precision is the total number of bits or digits in the representation of a number. accuracy is the number of correct bits or digits in a number. Given a certain representation on a computer, all numbers stored in that representation will have the same precision; however the accuracy of different numbers will vary, depending on the source and on the calculations done on them.

### What is the definition of accuracy in computer characteristics?

How correct an answer is. The accuracy obtained from calculations depends on using bug-free computer chips as well as the quality of the input. Contrast with precision, which refers to the number of digits, or exactness, in an answer.
