Changing the rounding rule to solve dirac offset on 0 for odd number of neurons. #38

When setting an odd number of neurons for the field, the dirac was not centered for x=0. This was due to the default FE_TONEAREST rounding method used by nearbyint() function.

Setting FE_DOWNWARD method allows to get the floor int rather than ceiling for exact midway (.5) between 2 int
