 # Statement of need
 
 In the 2008 revision of IEEE 754 [@IEEE754:2008], decimal floating-point arithmetic was standardized.
-These types are critical in applications where decimal numbers must be represented exactly, such as financial software.
+These types are critical in applications where decimal numbers must be represented exactly, such as financial software [@Cowlishaw:2003].
 Binary floating-point representations cannot precisely store common decimal values like 0.1, leading to subtle rounding errors that accumulate over repeated calculations.
-In accounting systems, this can result in discrepancies that violate regulatory requirements or erode user trust.
 Prior to Boost.Decimal, no cross-platform C++ library provided IEEE 754 decimal arithmetic or the associated types.
