Cassio fx100s how to convert dec to binary and hex to binary

Go to Ticalc.org and look for binary to decimal converter.

Press MODE 4 to select the BASE-N mode. Press one of DEC, HEX, BIN, or OCT to specify the input base, enter the number, then press one of the base keys to convert to that base.

First check your rounding by hitting the mode button, then hit F2 and make sure it says Auto beside Exact/Approx if not change it to Auto.

Then you can proceed

Type in 2009

Then hit 2nd then mode (produces a solid right facing arrow.)

Then type in Bin (using the alpha button)

Press enter

The answer should look like this
0b11111011001 ignore the 0b and that is your answer.

Press MODE 4 to enter the BASE-N mode. Press the BIN, OCT, DEC, or HEX button to specify the input number base, enter the number to be converted, then press the BIN, OCT, DEC, or HEX button to convert to that base. To enter the other hexadecimal digits, use the A, B, C, D, E, F buttons (the row of the keyboard beginning with the (-) key.

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

Hello,

You do not need to multiply by 1. If your calculator does not convert the number you just entered, try validating your entry by pressing = then convert it to hexadecimal.

Hope it helps

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.

Try this. Press MODE and then number 1 ... This worked to me. And then with DRG you can change to DEG, RAD or GRAD ... I hope I helped :)
