### What is the meaning of octal

The octal numeral system, or oct for short, is the base-8 number system, and uses the digits 0 to 7. Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three (starting from the right). For example, the binary representation for decimal 74 is 1001010, which can be grouped into (00)1 001 010 - so the octal representation is 112.
In the decimal system each decimal place is a power of ten. For example:
In the octal system each place is a power of eight. For example:
By performing the calculation above in the familiar decimal system we see why 112 in octal is equal to 64+8+2 = 74 in decimal.

Hope this helps

### How to convert a dinary number to a binary number using a casio fx-82MS calculator

Dinary? Never heard that one before. What is a dinary number? Anyway your calculator cannot perform the operations. The Casios can work in Binary (base 2), Octal (base 8), Decimal (base 10) and Hexadecimal (base 16). Some Sharps can do calculations in base 5 (pental).

### Converting from BASE-N to Decimal

If you want to convert from another base to decimal, press MODE 4 to enter the BASE-N mode, select the initial base (binary, octal, or hexadecimal), enter the number, then switch to decimal to see the value in decimal.
If you want to exit the BASE-N mode, press MODE 1 to switch to the computational model or MODE 2 for complex mode.

### How to get my fx-300es into decimal mode

I am not sure about what you want.
2. Decimal numeration as opposed to binary/octal/hexadecimal?

For the first case, set Input/Output IO mode to LineIO (SHIFT MODE 2:LineIO)
For the second case set Computational mode to COMP etc, but NOT to BASE-N

### How do you convert decimal numbers into binary?

Press MODE 4 to enter the BASE-N mode. Type in the decimal number, then press BIN to convert to binary. Press DEC to switch back to decimal for the next conversion.

You're limited to numbers in the range [-32768...32767] in binary. You can extend the range if you convert to octal or hexadecimal and then mentally convert each digit to three or four bits.

Hello desireejane,

One method is to do the following

1. Convert the octal, hexadecimal or binary to decimal.
2. Add or Subtract the decimal normally
3. Convert the result back to octal, hexadecimal or binary.

• Convert the octal to decimal:

public static long octalToDecimal(String octal) throws NumberFormatException {
// Initialize result to 0
long res = 0;

// Do not continue on an empty string
if (octal.isEmpty()) {
throw new NumberFormatException("Empty string is not an octal number");
}

// Consider each digit in the string
for (int i = 0; i < octal.length(); i++) {
// Get the nth char from the right (first = 0)
char n = octal.charAt(octal.length() - (i+1));

int f = (int) n - 48;
// Check if it's a valid bit
if (f < 0 || f > 7) {
// And if not, die horribly
throw new NumberFormatException("Not an octal number");
} else {
// Only add the value if it's a 1
res
+= f*Math.round(Math.pow(2.0, (3*i)));
}
}

return res;
}

### I'm trying to calculate base number equation

Hello,
You are victim of a confusion between terms. Base-n calculations are calculations using various numeration systems (bases) : binary (2), octal(8) hexadecimal (16) and decimal (10). What you want is how to calculate powers, logarithms, exponentials and these have also the notion of base; Log in base 10 is the common log, whereas natural logarithms, are logarithms in base e.
Back to your exemple: 5 times 5 and raise the whole to power 3?
In that case [(] 5 [x] 5 [)] [^] 3 or [X to the 3] if you have such key or
25 [^] 3, because 5x5 = 25

5 times (5 raised to power 3)
5[x] [( ] 5 [^] 3 [)] or 5 [^] 4 because of the rules about products of powers with the same base.

Hope it helps.

### Programming in c

To convert numbers you can use the printf() function
printf("%d", x'FF') hex to decimal
printf("%o", x'FF') hex to octal

If you want to save the value in another variables use sprintf
e.g

a = x'FF';
b = sprintf("%d",a)
