+mpdecimal is a package for correctly-rounded arbitrary precision decimal floating point arithmetic.
+
+libmpdec is a C implementation of the General Decimal Arithmetic Specification. The specification defines 
+a general purpose arbitrary precision data type together with rigorously specified functions and rounding 
+behavior. libmpdec conforms - with minor restrictions - to the IEEE 754-2008 Standard for Floating-Point 
+Arithmetic, provided that the appropriate context parameters are set. libmpdec++ has a thread local context 
+for inline operators and other functions that use the implicit context.
