  // Package strconv implements conversions to and from string representations
  // of basic data types.
  //
  // Numeric Conversions
  //
  // The most common numeric conversions are Atoi (string to int) and Itoa (int to string).
  //
  //	i, err := strconv.Atoi("-42")
  //	s := strconv.Itoa(-42)
  //
  // These assume decimal and the Go int type.
  //
  // ParseBool, ParseFloat, ParseInt, and ParseUint convert strings to values:
  //
  //	b, err := strconv.ParseBool("true")
  //	f, err := strconv.ParseFloat("3.1415", 64)
  //	i, err := strconv.ParseInt("-42", 10, 64)
  //	u, err := strconv.ParseUint("42", 10, 64)
  //
  // The parse functions return the widest type (float64, int64, and uint64),
  // but if the size argument specifies a narrower width the result can be
  // converted to that narrower type without data loss:
  //
  //	s := "2147483647" // biggest int32
  //	i64, err := strconv.ParseInt(s, 10, 32)
  //	...
  //	i := int32(i64)
  //
  // FormatBool, FormatFloat, FormatInt, and FormatUint convert values to strings:
  //
  // 	s := strconv.FormatBool(true)
  // 	s := strconv.FormatFloat(3.1415, 'E', -1, 64)
  // 	s := strconv.FormatInt(-42, 16)
  // 	s := strconv.FormatUint(42, 16)
  //
  // AppendBool, AppendFloat, AppendInt, and AppendUint are similar but
  // append the formatted value to a destination slice.
  //
  // String Conversions
  //
  // Quote and QuoteToASCII convert strings to quoted Go string literals.
  // The latter guarantees that the result is an ASCII string, by escaping
  // any non-ASCII Unicode with \u:
  //
  //	q := Quote("Hello, 世界")
  //	q := QuoteToASCII("Hello, 世界")
  //
  // QuoteRune and QuoteRuneToASCII are similar but accept runes and
  // return quoted Go rune literals.
  //
  // Unquote and UnquoteChar unquote Go string and rune literals.
  //
