For the printf command, the default format of the E argument is: « - »d.ddddE« - »dd
eg. 1.234E-05
In my case i dont need the leading zero in the exponent.
I want the output like this: 1.234E-5
Can i change the printf output with any argument? Do i have to make my own printf function? Or can i change the compilers printf command?
Maybe not the answer you're looking for, but...
Couldn't you simply post process the output of the printf to remove the offending '0' character before using the string...? Seems to me like that might the simplest way around your problem.
Just a thought...
Dave.
" ...post process the output of the printf ..."
Or sprintf to a buffer, and post-process that
Or if possible, change the receiving parser to be less picky, so that either format is acceptable.
My favorite references indicate that ANSI C standard behavior is to always have at least two decimal digits for the exponent. In that case, E+5 isn't technically even proper behavior on the part of the other compiler.
Peter,
Er du sikker paa at en '51 er den rette processor for dette job?
I really think that,based on the questions you have asked that you need to consider e.g. an ARM for this. The '51 is plain MISERABLE as a floating point processor due to the architecture being designed not for computing, but for control. Of course, if you are runnibg porocess for hours between each float, that will be another case.

Jeg skal bruge den indbyggede 24bit A/D konverter som er i ADuC845. Efter hvad jeg ved er der er endnu ikke kommet nogen ARM processor med indbygget 24 bit A/D konverter.
Men ellers tak for dit reply.

you need to read www.8052.com/faqs.phtml
since many of the bits from a 24 bit a/d are worthless you do not need floating point, you will not ever get more than 16 bits of precision whatever the resolution of your a/d is.
PS: a bit of Danish once a year is very nice, but, for the benefit of others, keep the important stuff in english
