Summary

Provides a low-level interface to the strconv package.

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.

Constants

Constants are variables with :const true in their metadata. Joker currently does not recognize them as special; as such, it allows redefining them or their values.
