Programming

Hi all,
i am trying to use C in unix platform to convert a double variable (floating point) to a string variable.

i tried using sprintf, ecvt, fcvt,gcvt.
but all gave me funny output or altered the content.

does anyone know how to convert the data and keep the original content.

for example, 3.3 or 3.33e2 in double to string

if anyone knows the ans, plas kindly post an example of the code.

thanks a lot.

This worked just fine for me:

Code:

#include<stdio.h>

int main() {
        double a=7.123451;
        char b[10];
        sprintf(b,"%lf",a);
        printf("%s\n",b);
}

[edit]
It's been a while since I did this sort of coding, so if there is anything wrong in the syntax, please point it out.
[/edit]

thanks for the reply.

but i am getting input from another function which i do not know what the content will be. for example, it may be 7.123451 or 7.1234e5.
so for sprintf, i will need to specify it is %f or %e.
do you know any function that do not have to specify the type , rather convert any floating point value.

thanks for helping

"%lf" works with both "%e" and "%f"

Code:

#include<stdio.h>

int main() {
        double a=7.1234e5,c=7.123451;
        char b[50],d[50];
        sprintf(b,"%lf",a);
        sprintf(d,"%lf",c);
        printf("b:%s\td:%s\n",b,d);
}

Can your input be anything else apart from what you've said it could be?

Also, moderators, can this be moved to the C programming section?
