6.1 Limitations
SINGULAR has the following limitations:
-
the characteristic of a prime field must be less or equal than 2147483629
-
the (weighted) degree of a monomial must be less or equal than 2147483647
-
the rank of any free module
must be less or equal than 2147483647
-
the maximal allowed exponent of a ring variable
depend on the ordering of the ring and is at least 32767.
-
the precision of long floating point numbers (for ground field
real )
must be less or equal than 32767
-
integers (of type
int ) have the limited range
from -2147483648 to 2147483647
-
floating point numbers (type
number from field real ) have
a limited range which is machine dependent. A typical range is -1.0e-38
to 1.0e+38. The string representation of overflow and underflow is
machine dependent, as well. For example "Inf " on Linux, or
"+.+00e+00 " on HPUX.
-
the length of an identifier is unlimited but
listvar
displays only the first 20 characters
-
statements may not contain more than 10000 tokens
-
All input to Singular must be 7-bit clean, i.e. special characters like the
the German Umlaute (ä, ö, etc.), or the French accent characters may
neither appear as input to SINGULAR, nor in libraries or procedure
definitions.
