- // 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 := strconv.Quote("Hello, 世界")
- // q := strconv.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.
- //
