Specifically

Additionally (before clamping) the reciprocal of negative infinity
    gives [-0.0, -0.0, -0.0, -0.0]; the reciprocal of negative zero gives
    [-Inf, -Inf, -Inf, -Inf]; the reciprocal of positive zero gives
    [+Inf, +Inf, +Inf, +Inf]; and the reciprocal of positive infinity
    gives [0.0, 0.0, 0.0, 0.0].
