Sorry but this calculator cannot do calculations in other numerations just decimal. To make sure examine the calculator looking for markings like BIN OCT HEX. If you do not find any (and you will not) then you can be sure that it does not perform base conversions.

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

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.

### Convert to binary to a decimal 111000

To convert from binary to decimal, we have to line up the numbers with the binary columns.

1 1 1 0 0 0
2^5 2^4 2^3 2^2 2^1 2^0
32 16 8 4 2 1

32 + 16 + 8 + 0 + 0+ 0 = 56

Good luck.

### Convert decimal fraction to binary

None of these solutions answer his question. When converting a fraction or any number with decimal places to Binary, the TI-89 gives "Error: Domain error." For example, entering .6875 [2ND][MATH][BASE][BIN] does not work. I haven't found a way to do it with built in functions. In order to do these types of conversions, I use the following method.

Convert: 0.6875 to Binary
- left of decimal is a 0, so write down a 0, then a decimal point: (0.)
- multiply .6875 x 2 = 1.375 left of decimal is 1, write a 1: (0.1)
- drop the 1 and multiply .375 x 2 = .75 left of decimal is 0. write a 0: (0.10)
- multiply .75 x 2 = 1.5 left of decimal is 1, write a 1: (0.101)

- drop the 1, multiple .5 x 2 = 1. left of decimal is 1, write a 1: (0.1011).
- since there is no more fraction, the final answer is (0.1011). Hope this helps.

### How to convert binary with point to decimal

1) Look at the following numbers before trying to convert binary to decimal. Each of them represent the value in a binary number from left to right.
128-64-32-16-8-4-2-1

2) Look at your binary number, for this example lets use 10010010. For each one add the corresponding number from step 1, the number you come out with is the conversion.

So: 10010010 -> 128+16+2 -> 146
10010010 = 146

### How to get from dec. to binary

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.

### 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.
