Append_formatted_date appends date dt, formatted by format_string.

Types

type Numberfmt

type Numberfmt struct {
	// contains filtered or unexported fields
}

Numberfmt is the object that is used to output a number with a format string. It contains information from format string, like digit placeholders count. It also contains the number as string, before formatting.

Number formatting is made in two passes.
  - First pass: Get_format_info() parses the format string to count the number of placeholders. Result is put in Numberfmt object.
  - Fill_int64(), Fill_float64(), or Fill_MyQuad() puts the number to format in Numberfmt as plain string.
  - Set_langinfo() puts decimal point symbol and group separator symbol in Numberfmt.
  - Second pass: Append_formatted_number() makes a second parsing to replace placeholders by digits, writing result into target byte slice.

Normally, errors occur only when number is in exponent notation, or Nan or Infinity. But this should not happen with the numbers being in SQL INT, BIGINT, FLOAT or NUMERIC range.
