With num = 1023 the result will be a number with 10 digits which is near the capacity of a long (better use int32). you may use uint64
but the problem will remain the same, end will be a million.
Why don't you use %b format in sprintf?
Converting a binary into a decimal is only needed when you want to print it as a string, so why not converting into a character string?
A million would be enough for me, but with int32, 1023 is also the limit. And I cant find any argument for int64 which is accepted by Creator.
The format %b is also not working.
I dont want to convert binary into decimal, I want to convert decimal into binary.
What do you mean by character string? I want to calculate some other things with my binary number in the end.
All (most) numbers represented in a µProcessor are in hexadecimal. Only when communicating with one of us humans a conversion is needed. Human readable are ASCII characters only where the digits "0" to "9" are represented by the values 0x30 to 0x39 or 48dec to 57dec. So a number represented by a string of digits must be converted to the internal hex representation.
Where do the numbers come from you want to convert?
There are of course C-functions or macros for conversion like atii() and scanf(), have a look into a C-manual like this one.
What do you mean with " I cant find any argument for int64 which is accepted by Creator."?
Thanks for the link, I will have a look after lunch.
My numbers are real and imaginary part of a measured impedance. But the numbers have to be converted into twos complement. Therefore I need to convert my decimal value into binary, invert every 0 to 1 and every 1 to 0 and then sum a one (this is the procedure to convert a number into twos complement) Works fine with a pencil and a paper, but I am stuck at the conversion into binary.
Since it worked for values up to 1023 I thought it might be a problem with the value-size. but int32 also doesnt work.
By "argument" I mean the "%" in sprintf. For int I use "%d" and for int32 I use "%ld", but I cant find anything for int64.
Maybe its worth a try to increase the size of the value once more.
Sorry Bob, but your link wasnt helpfull for me :(
I found an unconventional method which is working nicely.
Because I just need to convert 16 bit values, where the 16th bit is set, the following method is appropriate:
value -65536 (1000000000000000 binary) = value in twos complement.
Sounds weird, but it is working ;)
