printf, padding integral double values

[Daniel Molina Wegener]

Hello,

How can I pad integral values on double variables with
printf.

I know that %.nf or %.ng sets the precision. But I want to
pad the integral value with zeroes, like 001.023 or 032.012.

Any way to do this with printf?.

Regards.

#include <stdio.h>

int main (void)
{
printf("%0*.*f\n", 6+1, 3, 1.23);
return 0;
}

Cheers

#include <stdio.h>

int main(void)
{
double x[] = { 1.023, 32.012 };
size_t i;

printf("[output]\n");
for (i = 0; i < sizeof x / sizeof *x; i++)
printf("%%g: %g, %%f %f, %%.3f %.3f, %%07.3f %07.3f\n",
x[i], x[i], x[i], x[i]);
return 0;
}

[output]
%g: 1.023, %f 1.023000, %.3f 1.023, %07.3f 001.023
%g: 32.012, %f 32.012000, %.3f 32.012, %07.3f 032.012
