#include <conio.h>

int main(void)

{

char*string;

double value;

int dec, sign;

int ndig = 10;

clrscr();

value = 9.876;

string = ecvt(value, ndig, &dec, &sign);

printf("string = %s dec = %d \

sign = %d\n", string, dec, sign);

value = -123.45;

ndig= 15;

string = ecvt(value,ndig,&dec,&sign);

printf("string = %s dec = %d sign = %d\n",

string, dec, sign);

value = 0.6789e5;

ndig = 5;

string = ecvt(value,ndig,&dec,&sign);

printf("string = %s dec = %d\

sign = %d\n", string, dec, sign);

return 0;
