| Description | sumdevV = sum( |Xi - Yi| )
V?_sumdevVwSaturation is almost identical to V?_sumdevV, except for the treatment of infinities and NAN values. While V?_sumdevV may overflow to INF and will return NAN, if any input element is a NAN, V?_sumdevVwSaturation will saturate possible overflow into HUGE_VAL and treats input values of ±NAN as ±HUGE_VAL. |

| Return value | sum of the absolute deviations. |
