syntax bug in real/complex: use of exponent e demands a . in mantissa

[gorzel]

Input without a . in the mantissa is not recognized, only the exponent survives:

> ring ri = (complex,10,i),(x),(dp(1),C);
> (123.e+10);
0.123e+13
>  (123e+10);   // wrong result
10
> (123.e-13);
0.0000000000123
> (123e-13);   // wrong 
-13
>  (123.e-18);
0.123e-15

Not a bug: the . is required according to ​http://www.singular.uni-kl.de/Manual/latest/sing_140.htm

Shouldn't we warn in case of wrong input???
