How can i change from binary to hexadecimal in fx82es

a bit is a computer term which can be either 1 or zero. so a 40 bit password would be something like 1100011000011101100110010100101011001010 or any other combination of 40 1's and 0's.. familiarity with Binary numbers would help here.. not easy to remember though.
Hexadecimal is another method used to help simplify binary notation and we use the digits 0-9 and the letters A-F to represent a grouping of 4 binary digits or 4 bits. so the 40 digit string above could be represented as 10 Hexadecimal digits as follows
C61D99499ACA - which is a little easier to remember. ASCII is a standard by which we use 8 bits ( 8 binary digits or 2 hexadecimal digits ) to represent the numbers, letters and symbols on our keyboard... using a 5 letter password such as Bird? ( including the question mark) would be the equivalent of the following hexadecimal representation
42 69 72 64 3F or the binary/bit representation
0100001001101001011100100110010000111111

Hope this helps.

Sorry to be the carrier of bad news but the Casio FX-83 GT Plus does not have a baseN calculation mode. You cannot do any arithmetic in binary, octal or hexadecimal numeration.

What make and model calculator?

If you want to do it by hand, each hexadecimal digit is four binary digits:

0 = 0000
1 = 0001
2 = 0010
3 = 0011
4 = 0100
5 = 0101
6 = 0110
7 = 0111
8 = 1000
9 = 1001
A = 1010
B = 1011
C = 1100
D = 1101
E = 1110
F = 1111

Press 0 ALPHA [H] 0 1 0 0 1 1 1 0 MODE F2, scroll down to the "Base" line, press right-arrow, select "BIN" then press ENTER ENTER ENTER.

As a note, 01001110 looks suspiciously like a binary number.

How about 4 thumbs??

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;
}

Hello,
In the FX300Ms manual, the same for the FX350MS, there is no way to use base-n (binary, octal, hexadecimal) calculations.
Sorry.
