NumTraits Class Reference
Holds some data about the various numeric (i.e. scalar) types allowed by Eigen.
|T ||the numeric type about which this class provides data. Recall that Eigen allows only the following types for T: |
double (especially useful to enforce x87 arithmetics when SSE is the default).
The provided data consists of:
- A typedef Real, giving the "real part" type of T. If T is already real, then Real is just a typedef to T. If T is
std::complex<U> then Real is a typedef to U.
- A typedef FloatingPoint, giving the "floating-point type" of T. If T is
int, then FloatingPoint is a typedef to
double. Otherwise, FloatingPoint is a typedef to T.
- An enum value IsComplex. It is equal to 1 if T is a
std::complex type, and to 0 otherwise.
- An enum HasFloatingPoint. It is equal to
0 if T is
int, and to
