can you be more specific

what kind of input and what kind of output do you expect

how do you want to store the numbers

as the title implies
That's not what the title implies. Not at all. The title asks how you can find a decimal point (that's the point separating the whole number from the fractional part)

how do you fetch the ASSCI numbers from a string
You don't? You already have all the ASCII values when looking at a string

;compile c

#include <stdio.h>

int main() {
  // Create an example string.
  char str[2048];
  sprintf(str, "%f", 23.78254891);
  puts("Original string:");
  puts(str);

  // Iterate to the demimal point or to
  // the end of the string if there is none.
  size_t idx = 0;
  while (str[idx] != '.' &&
         str[idx] != '\0')
    idx++;

  // Re-terminate the string to cut off the trailing digits.
  // If there were none, this is a no-op.
  str[idx] = '\0';

  puts("Clipped string:");
  puts(str);
}

Since strings are null terminated, you can slap a null terminator wherever you want to clip it.
