abstract fun decimalNumber(wholeLength: IntRange = 1..19, fractionLength: IntRange = 0..9, fractionScale: Int = 9, builder: DecimalNumberParserBuilder.() -> Unit = {}): Unit
Parse a decimal number.
If the minimum fractionLength is zero, a decimal separator isn't required.
wholeLength - the number of digits to parse from the whole part, excluding sign
fractionLength - the number of digits to parse from the fraction part
fractionScale - the number of digits to normalize the fraction to -- by default 9, indicating nanoseconds
