// 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.
|
|
//
