You can convert this in a number different of ways, all giving the same result if applied properly. However people from the olden days that still used 8-bit computers often used following:

1.Split the binary number in groups of four digits, adding leading zeros if necessary. 11001100 => (1100) (1100).
2. Given the individual bits have values 8, 4, 2, 1 when set, convert the groups individually 1100 = 8+4 = 12. In your case, both groups have the same value,
3. Multiply the value for the left group by 16 and add the right group's value:12 * 16 + 12 = 192 + 12 = 204.
It helps if you know the multiples 1*16, 2*16, ...., 15*16 by heart.

### Can you round 3,150,000 to 2 decimal places

Huh?
To round off a number to 2 decimal places.... you would have to have a decimal. Your number of 3,150,000 implies 3,150,000.00

There is no rounding in this case. It is simply adding a decimal and two zeros after the decimal.

### How can I round 0.4678476 to the nearest dollar?

When rounding, we always look at the number in the position directly to the right of the position we are interested in. In this case, the whole dollar is the number immediately to the left of the decimal, so we look at the number immediately to the right of the decimal. If this number is 5 or more, we add 1 to the number to the left of the decimal. If the number to the right of the decimal is 4 or less, we do not add 1 to the number to the left of the decimal.

In this case, the number is 4, so it rounds down to 0.

Good luck,

Paul

### FX 82 es scientific calculator. How I get decimal expansion of numbers?

Meaning what, exactly?
If you want a decimal representation of an exact number, press the SD key to switch from exact to approximate (decimal). If you want to expand a decimal number in powers of 10, separate all the digits, multiply every digit by a power of 10 with exponent equal to its position as counted from the decimal mark -1. To the left of the decimal mark, the exponent is positive. To the right of the decimal mark, the exponent is negative. Sum everything
Example
345.678 =3*10^(3-1)+4*10^(2-1)+5*10^(1-1)+6*10(-1)+7*10^(-2)+8*10^(-3)

### Define algebra:decimal

Decimal is the base-10 notational system for representing real numbers. The expression of a number using the decimal system is called its decimal expansion, examples of which include 1, 13, 2028, 12.1, and 3.14159.

Each of the arabic numerals 0 to 9 is called a decimal digit, and the period placed to the right of the units place in a decimal number is called the decimal point (or, in the case that a comma is instead used for this purpose, the decimal comma).

The decimal is a way of managing numbers that has ten as a starting point, or base. It is sometimes called the base ten or denary numeral system. The word "decimal" is also used instead of the word "period" to point out the dot that is sometimes used separates the positions of the numbers in this system. Almost everyone uses this nowadays and prefers the convenience of it probably because it shows up most often in calculations in nature and has "one" as another starting point for the system. The number one is usually the easiest to work with in calculations.

### Explain "CUT", "UP", "5/4"

CUT: Values are cut off to the number of decimal places speicified by the current Decimal Place Selector setting

UP: Values are rounded up to the number of decimal places speicified by the current Decimal Place Selector setting

5/4: Values are rounded off (0,1,2,3,4 are cut off; 5,6,7,8,9 are rounded up) to the number of decimal places speicified by the current Decimal Place Selector setting

### Convert .714285 to the fraction 5/7?

Say you have a repeating decimal number 0.714285 714285 714285 etc. You identify the period (the repeating part) and in this case it is 714285.
Y
ou count the number of decimal places in the period: here it is 6. Your equivalent fraction is
Fraction= period/(99...9) where the number of 9's in the denominator is equal to the number of decimal places in the period. For this case, that is 6.
Thus
0.714285 714285 714285 etc.= 714285 / 999999

Reduce the fraction and you will find 5/7

This technique works for a repeating decimal number where the period starts just after the decimal mark.

If the periodic part does not start right after the decimal mark there are modifications to be made.

### How to round the fig. in Excel 2007 E.g. 12350*32.75% = 4044.625 I want it to be rounded to nearer rupee. If the decimal is lesser than 50, rounded fig. should be lower Rupee if the decimal is more than 50...

The function is called ROUND. It has 2 arguments, (1) the original number and (2) the number of decimal digits. Here is the Excel's help: ROUND(number,num_digits) The number you want to round. None. num_digits The number of digits to which you want to round number. If num_digits is greater than 0 (zero), then number is rounded to the specified number of decimal places. If num_digits is 0, then number is rounded to the nearest integer. If num_digits is less than 0, then number is rounded to the left of the decimal point.
So for your case use this in a cell "=ROUND(12350*32.75%, 0)" without quotes, where I assume one or both numbers will come from other cells. -Ken
