Expression conversion: Convert_Frac_Cons

ALIAS uses a special mechanism to convert an expression into an equivalent C++ sentence that can be interval evaluated. This conversion is based on the conversion of the expression into a string in which all mathematical functions are substituted by their interval equivalent. This causes a problem if rational numbers are present in the expression as rational such as 1/6 will lead to 0 in C++. This procedure returns a string that describes the interval equivalent of the expression in which rational such as 1/6 as 1./6. and constant such as Pi have been converted into their C++ equivalent. For example
