| Description | ssqdevV = sum( (Xi - Yi)2 )
The deviation of each element of X from the corresponding element of Y is calculated and the squares of the deviations summed up and returned.
V?_ssqdevVwSaturation is almost identical to V?_ssqdevV, except for the treatment of infinities and NAN values. While V?_ssqdevV may overflow to INF and will return NAN, if any input element is a NAN, V?_ssqdevVwSaturation will saturate possible overflow into HUGE_VAL and treats input values of ±NAN as ±HUGE_VAL. |

| Return value | sum of the squares of the deviations. |
