seq: use BigDecimal to represent floats (#2698) * seq: use BigDecimal to represent floats Use `BigDecimal` to represent arbitrary precision floats in order to prevent numerical precision issues when iterating over a sequence of numbers. This commit makes several changes at once to accomplish this goal. First, it creates a new struct, `PreciseNumber`, that is responsible for storing not only the number itself but also the number of digits (both integer and decimal) needed to display it. This information is collected at the time of parsing the number, which lives in the new `numberparse.rs` module. Second, it uses the `BigDecimal` struct to store arbitrary precision floating point numbers instead of the previous `f64` primitive type. This protects against issues of numerical precision when repeatedly accumulating a very small increment. Third, since neither the `BigDecimal` nor `BigInt` types have a representation of infinity, minus infinity, minus zero, or NaN, we add the `ExtendedBigDecimal` and `ExtendedBigInt` enumerations which extend the basic types with these concepts. * fixup! seq: use BigDecimal to represent floats * fixup! seq: use BigDecimal to represent floats * fixup! seq: use BigDecimal to represent floats * fixup! seq: use BigDecimal to represent floats * fixup! seq: use BigDecimal to represent floats

seq: compute correct width for scientific notation Change the way `seq` computes the number of digits needed to print a number so that it works for inputs given in scientific notation. Specifically, this commit parses the input string to determine whether it is an integer, a float in decimal notation, or a float in scientific notation, and then computes the number of integral digits and the number of fractional digits based on that. This also supports floating point negative zero, expressed in both decimal and scientific notation.

seq: use BigDecimal to represent floats (#2698) * seq: use BigDecimal to represent floats Use `BigDecimal` to represent arbitrary precision floats in order to prevent numerical precision issues when iterating over a sequence of numbers. This commit makes several changes at once to accomplish this goal. First, it creates a new struct, `PreciseNumber`, that is responsible for storing not only the number itself but also the number of digits (both integer and decimal) needed to display it. This information is collected at the time of parsing the number, which lives in the new `numberparse.rs` module. Second, it uses the `BigDecimal` struct to store arbitrary precision floating point numbers instead of the previous `f64` primitive type. This protects against issues of numerical precision when repeatedly accumulating a very small increment. Third, since neither the `BigDecimal` nor `BigInt` types have a representation of infinity, minus infinity, minus zero, or NaN, we add the `ExtendedBigDecimal` and `ExtendedBigInt` enumerations which extend the basic types with these concepts. * fixup! seq: use BigDecimal to represent floats * fixup! seq: use BigDecimal to represent floats * fixup! seq: use BigDecimal to represent floats * fixup! seq: use BigDecimal to represent floats * fixup! seq: use BigDecimal to represent floats
