parse


Description:

public static int parse (string str)

Converts the string to its equivalent int representation

Function discards any whitespace characters until first non-whitespace character is found. Then it takes as many characters as possible to form a valid integer number representation and converts them to integer value. The valid integer value consists of the following parts:

  • (optional) plus or minus sign
  • numeric digits

Example: String to int:

public static int main (string[] args) {
// Output: ``10``
print ("%d\n", int.parse ("10"));

// Output: ``10``
print ("%d\n", int.parse ("10"));

// Output: ``10``
print ("%d\n", int.parse ("10xx"));

// Output: ``0``
print ("%d\n", int.parse ("A"));

// Output: ``0``
print ("%d\n", int.parse ("a"));

// Output: ``0``
print ("%d\n", int.parse ("x11"));

// Output: ``2147483647``
print ("%d\n", int.parse ("999999999999999999999999999999999"));

return 0;
}
