How to write float to string function using mikroC?

[youstron]

when i'm displaying float result on lcd, when the number is less than one ,lcd showing result interms of 'e' .. can any one know how to display 0.(zero point something) values.Can any one says the logic to write the own float to string function using mikroC .. hoping for the best answer

char str[20] = "";
float f = 4.5;
sprintf(str, "%f", f);

i heard that it takes more than 40% of the memory if we use sprintf..

if you are using is an AVR core must include libprintf_flt.a, libprintf_min.a, and flags-Wl,-u, vfprintf-lprintf_flt-lm, of course this is for AVRStudio. Mind you I'm just guessing that you are using AVR is not clear in your post

Re: floattostr() problem

Similar to the standard C sprintf() function but safer, since it calculates the maximum space required and allocates memory to hold the result. The returned string should be freed with g_free() when no longer needed.

If possible, use snprintf -- it gives an easy way to measure the size of data that would be produced so you can allocate space.
If you really can't do that, another possibility is printing to a temporary file with fprintf to get the size, allocate the memory, and then use sprintf. snprintf is definitely the preferred method though.

d=(tanA*tanB/(tanA+tanB))
i want to write this equation using mikroc.how can i write this?plz help me.
(in here A=motor1*0.1 & B=motor2*0.1)
motor1 & motor2 are variables.

There is tan() function which needs rad value. If you use trigonometry library then you can use sinE3()/cosE3() for getting tan value. These two functions take arguments in degrees.
