// 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.
