Write a function myatof(str_digit) that takes as input a string of digits and convert it into its equivalent floating point value with no more than 4 decimal places.

Ex: myatof(324.1234) returns the floating value 324.1234.

The function prototype is given below and assume that SIZE has been defined to be 9 (i.e., #define SIZE 9).

double myatof(char str_digit[SIZE]);
