Hi,

Can someone please guide me how I can convert a decimal number to binary using the Casio FX-115ES Scientific Calculator?

Press MODE 4 to enter the BASE-N mode. If the display doesn't say Dec, press SHIFT DEC (the x^2 key) to set base 10. Enter the number to convert. Press SHIFT BIN (the log key) to switch to base 2.

Each time you switch the base the current value is redisplayed in that new base.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

Let's do the preocess so it will work on any calculator.

As an example, convert 68 from decimal to binary.

The decimal columns are 10^0, 10^1, 10^2, 10^3, etc.

The binary columns are 2^0, 2^1, 2^2, 2^3, etc.

Flipping to the normal left to right, we get 2^6, 2^5, 2^4, 2^3, 2^2, 2^1, 2^0.

64 32 16 8 4 2 1

We divide our number, 68, by 64, and get 1 with a remainder of 4. We next divide our remainder by 32, 16, 8, and finally 4, where we get 1 with no reminder.

In binary, this works out to 1000100. To check, we multiply the ones by the respective column values and get 64 + 4 = 68.

Good luck.

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.

You can't. It can only convert integral numbers to binary base, but not fractions.

If you're already in decimal mode, press SHIFT BIN to switch to binary mode.

To convert a number from decimal to binary, press MODE 4 to switch to BASE-N mode. You'll find yourself in decimal mode. Enter the number to convert, press =, then press SHIFT [BIN] (the log key) and see the number in binary. To convert another number, press SHIFT [DEC] to return to decimal, enter the number, press =, then press SHIFT [BIN]. An analogous process works for hexadecimal and octal as well.

To return to "normal" use, press MODE 1 for COMP mode or MODE 2 for complex mode.

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.

change your mode to binary , then enter your decimal no in dec link and then press bin link you can get the binary equivalent

You can convert between Standard Form (with fractions and pi) or
Decimal form by using the "S<->D" button. Use Mode 1 if you
mostly prefer fraction answers and you can use the SD button to convert
to decimal or use Mode 2 if you mostly prefer decimal answers and use
the SD button to see the fraction.

I hope this helps and good luck!
