Decimal data type

[bramvbilsen]

Describe the feature

A new numerical data type called Decimal that follows the IEEE 754-2008 spec

Use Case

Number stored in the proposed Decimal type allow for storing data sensitive to impression. This is particularly useful when working with financial data. Currently available data types, such as floats, are not suitable for this due to rounding errors and impression being inherent to the type.

Proposed Solution

Add a new Decimal type which strictly follows the IEEE 754-2008 spec (https://en.wikipedia.org/wiki/IEEE_754).
