new(*args) public

Create a new BigDecimal object.

initial

The initial value, as an Integer, a Float, a Rational, a BigDecimal, or a String.

If it is a String, spaces are ignored and unrecognized characters terminate the value.

digits

The number of significant digits, as an Integer. If omitted or 0, the number of significant digits is determined from the initial value.

The actual number of significant digits used in computation is usually larger than the specified number.

Exceptions

TypeError	If the `initial` type is neither Integer, Float, Rational, nor BigDecimal, this exception is raised.
TypeError	If the `digits` is not an Integer, this exception is raised.
ArgumentError	If `initial` is a Float, and the `digits` is larger than Float::DIG + 1, this exception is raised.
ArgumentError	If the `initial` is a Float or Rational, and the `digits` value is omitted, this exception is raised.
