+1.0.14 (<date>)
+* Improved the C-source output: complex numbers are printed correctly (using
+ the STL complex<> template or cln::complex()), rational numbers use cl_RA()
+ in the CLN output, and small integers are printed in a more compact format
+ (e.g. "2.0" instead of "2.0000000e+00").

1.0.13 (27 January 2003)
* Contracting epsilon tensors with Euclidean indices now works.
* Improved dummy index symmetrization in sums.
The above example will produce (note the @code{x^2} being converted to @code{x*x}):
@example
-float f = (3.000000e+00/2.000000e+00)*(x*x)+4.500000e+00;
-double d = (3.000000e+00/2.000000e+00)*(x*x)+4.500000e+00;
-cl_N n = (cln::cl_F("3.0")/cln::cl_F("2.0"))*(x*x)+cln::cl_F("4.5");
+float f = (3.0/2.0)*(x*x)+4.500000e+00;
+double d = (3.0/2.0)*(x*x)+4.5000000000000000e+00;
+cl_N n = cln::cl_RA("3/2")*(x*x)+cln::cl_F("4.5_17");
