BEGIN_NAMESPACE_QPOASES const real_t EPS = 2.221e-16

Numerical value of machine precision (min eps, s.t. 1+eps > 1). Note: this value has to be positive!

const real_t INFTY = 1.0e20

Numerical value of infinity (e.g. for non-existing bounds). Note: this value has to be positive!

const unsigned int MAX_STRING_LENGTH = 160

Maximum number of characters within a string. Note: this value should be at least 41!

const real_t ZERO = 1.0e-25

Numerical value of zero (for situations in which it would be unreasonable to compare with 0.0). Note: this value has to be positive!
