converting binary to hex

Is there an efficient way to do this? Right now im just converting the binary to base 10 and from there converting it to hex. It takes too much time.

you could make a program to do it for you?

or...do this:
add 80 for the 7th bit, 40, for the 6th. 20 for the 5th, 10 for the fourth, 08 for the 3rd, 04 for the 2nd, 02 for the 1st, 01 for the 0th...

0th? idk man just go with the flow...hope that helps...

Binrary to hex is simple in your head. It easier than to decimal.

You really only have to convert 0-15 nothing else

It's not hard really.

0000b = 00h
0001b = 01h
0010b = 02h
0011b = 03h
0100b = 04h
0101b = 05h
0110b = 06h
0111b = 07h
1000b = 08h
1001b = 09h
1010b = 0Ah
1011b = 0Bh
1100b = 0Ch
1101b = 0Dh
1110b = 0Eh
1111b = 0Fh

In Basic, I find it easier to go from one to the other via decimal.

Code: Select all

{1,0,1,0,1,0,0,1->L1
sum(L1seq(2^I,I,dim(L1),1,-1
int(16fPart(Ansseq(16^I,I,int(-dim(L1)/4),-1

1011b = 0Bh
1100b = 0Ch
1101b = 0Dh
1110b = 0Eh
1111b = 0Fh

So, let's say you want to convert this 32-bit #:

Code: Select all

01101010100101011101111101010101

Break it up into nibbles:

Code: Select all

0110 1010 1001 0101 1101 1111 0101 0101

And convert each nibble:

Code: Select all

6    A    9    5    D    F    5    5

%01101010100101011101111101010101 == $6A95DF55

And this is one reason why hexadecimal is the preferred base-of-choice when it comes to machine code!

(excluding those hard-core binary-ists

)

Moved to General TI, because it's not directly related to programming help.

I know. I am cleaning up the programming help section, which should be modded strictly... I was just a little slobby in the last time, so things got out of hand.
