AppendBool appends "true" or "false", according to the value of b,
to dst and returns the extended buffer.
AppendComplex appends the result of FormatComplex to dst.
It is here for the runtime.
There is no public strconv.AppendComplex.
AppendFloat appends the string form of the floating-point number f,
as generated by [FormatFloat], to dst and returns the extended buffer.
AppendInt appends the string form of the integer i,
as generated by [FormatInt], to dst and returns the extended buffer.
AppendUint appends the string form of the unsigned integer i,
as generated by [FormatUint], to dst and returns the extended buffer.
Atoi is equivalent to ParseInt(s, 10, 0), converted to type int.
FormatBool returns "true" or "false" according to the value of b.
FormatComplex converts the complex number c to a string of the
form (a+bi) where a and b are the real and imaginary parts,
formatted according to the format fmt and precision prec.
The format fmt and precision prec have the same meaning as in [FormatFloat].
It rounds the result assuming that the original was obtained from a complex
value of bitSize bits, which must be 64 for complex64 and 128 for complex128.
FormatFloat converts the floating-point number f to a string,
according to the format fmt and precision prec. It rounds the
result assuming that the original was obtained from a floating-point
value of bitSize bits (32 for float32, 64 for float64).
The format fmt is one of
- 'b' (-ddddp±ddd, a binary exponent),
- 'e' (-d.dddde±dd, a decimal exponent),
- 'E' (-d.ddddE±dd, a decimal exponent),
- 'f' (-ddd.dddd, no exponent),
- 'g' ('e' for large exponents, 'f' otherwise),
- 'G' ('E' for large exponents, 'f' otherwise),
- 'x' (-0xd.ddddp±ddd, a hexadecimal fraction and binary exponent), or
- 'X' (-0Xd.ddddP±ddd, a hexadecimal fraction and binary exponent).
The precision prec controls the number of digits (excluding the exponent)
printed by the 'e', 'E', 'f', 'g', 'G', 'x', and 'X' formats.
For 'e', 'E', 'f', 'x', and 'X', it is the number of digits after the decimal point.
For 'g' and 'G' it is the maximum number of significant digits (trailing
zeros are removed).
The special precision -1 uses the smallest number of digits
necessary such that ParseFloat will return f exactly.
The exponent is written as a decimal integer;
for all formats other than 'b', it will be at least two digits.
FormatInt returns the string representation of i in the given base,
for 2 <= base <= 36. The result uses the lower-case letters 'a' to 'z'
for digit values >= 10.
FormatUint returns the string representation of i in the given base,
for 2 <= base <= 36. The result uses the lower-case letters 'a' to 'z'
for digit values >= 10.
ParseBool returns the boolean value represented by the string.
It accepts 1, t, T, TRUE, true, True, 0, f, F, FALSE, false, False.
Any other value returns an error.
ParseComplex converts the string s to a complex number
with the precision specified by bitSize: 64 for complex64, or 128 for complex128.
When bitSize=64, the result still has type complex128, but it will be
convertible to complex64 without changing its value.
The number represented by s must be of the form N, Ni, or N±Ni, where N stands
for a floating-point number as recognized by [ParseFloat], and i is the imaginary
component. If the second N is unsigned, a + sign is required between the two components
as indicated by the ±. If the second N is NaN, only a + sign is accepted.
The form may be parenthesized and cannot contain any spaces.
The resulting complex number consists of the two components converted by ParseFloat.
The errors that ParseComplex returns have concrete type [*NumError]
and include err.Num = s.
If s is not syntactically well-formed, ParseComplex returns err.Err = ErrSyntax.
If s is syntactically well-formed but either component is more than 1/2 ULP
away from the largest floating point number of the given component's size,
ParseComplex returns err.Err = ErrRange and c = ±Inf for the respective component.
ParseFloat converts the string s to a floating-point number
with the precision specified by bitSize: 32 for float32, or 64 for float64.
When bitSize=32, the result still has type float64, but it will be
convertible to float32 without changing its value.
ParseFloat accepts decimal and hexadecimal floating-point numbers
as defined by the Go syntax for [floating-point literals].
If s is well-formed and near a valid floating-point number,
ParseFloat returns the nearest floating-point number rounded
using IEEE754 unbiased rounding.
(Parsing a hexadecimal floating-point value only rounds when
there are more bits in the hexadecimal representation than
will fit in the mantissa.)
The errors that ParseFloat returns have concrete type *NumError
and include err.Num = s.
If s is not syntactically well-formed, ParseFloat returns err.Err = ErrSyntax.
If s is syntactically well-formed but is more than 1/2 ULP
away from the largest floating point number of the given size,
ParseFloat returns f = ±Inf, err.Err = ErrRange.
ParseFloat recognizes the string "NaN", and the (possibly signed) strings "Inf" and "Infinity"
as their respective special floating point values. It ignores case when matching.
ParseInt interprets a string s in the given base (0, 2 to 36) and
bit size (0 to 64) and returns the corresponding value i.
The string may begin with a leading sign: "+" or "-".
If the base argument is 0, the true base is implied by the string's
prefix following the sign (if present): 2 for "0b", 8 for "0" or "0o",
16 for "0x", and 10 otherwise. Also, for argument base 0 only,
underscore characters are permitted as defined by the Go syntax for
[integer literals].
The bitSize argument specifies the integer type
that the result must fit into. Bit sizes 0, 8, 16, 32, and 64
correspond to int, int8, int16, int32, and int64.
If bitSize is below 0 or above 64, an error is returned.
The errors that ParseInt returns have concrete type [*NumError]
and include err.Num = s. If s is empty or contains invalid
digits, err.Err = [ErrSyntax] and the returned value is 0;
if the value corresponding to s cannot be represented by a
signed integer of the given size, err.Err = [ErrRange] and the
returned value is the maximum magnitude integer of the
appropriate bitSize and sign.
ParseUint is like [ParseInt] but for unsigned numbers.
A sign prefix is not permitted.
RuntimeFormatBase10 formats u into the tail of a
and returns the offset to the first byte written to a.
It is only for use by package runtime.
Other packages should use AppendUint.
IntSize is the size in bits of an int or uint value.
