Class NDDivision

Namespace

NumSharp.Utilities

Assembly

NumSharp.dll

floor-division and remainder helpers matching NumPy's floor_div_@TYPE@ (loops_arithmetic.dispatch.c.src), integer remainder (loops_modulo.dispatch.c.src), and the floating-point npy_floor_divide@c@ / npy_remainder@c@ (Python-divmod port in npy_math_internal.h.src).

Semantics replicated exactly:

• Integer divide/modulo by zero returns 0 (NumPy raises a RuntimeWarning but yields 0, never throwing — C#'s DivideByZeroException must not surface).
• Signed integer floor-division rounds toward negative infinity (Python //), not toward zero like C# /; MIN // -1 wraps to MIN (overflow), matching NumPy's npy_set_floatstatus_overflow(); return NPY_MIN.
• Signed integer remainder uses the floored (Python) sign convention: the result has the sign of the divisor; MIN % -1 == 0.
• Float floor-division/modulo follow CPython's divmod (fmod, sign-fixup, snap-to-nearest-integer), so a // 0.0 is ±inf/nan (not forced NaN) and edge cases like 0.7 // 0.1 == 6.0 and -2.0 // inf == -1.0 match.
