Edit Question
Title
Body
I am building an array with cython element by element. I'd like to store the constant np.inf (or -1 * np.inf ) in some entries. However, this will require the overhead of going back into Python to look up inf . Is there a libc.math equivalent of this constant? Or some other value that could easily be used that's equivalent to (-1*np.inf) and can be used from Cython without overhead? EDIT example, you have: cdef double value = 0 for k in xrange(...): # use -inf here -- how to avoid referring to np.inf and calling back to python? value = -1 * np.inf
