How VecPointwiseSign() should handle zero value

Synopsis

typedef enum {
  VEC_SIGN_ZERO_TO_ZERO,
  VEC_SIGN_ZERO_TO_SIGNED_ZERO,
  VEC_SIGN_ZERO_TO_SIGNED_UNIT,
} VecSignMode;

Values

• VEC_SIGN_ZERO_TO_ZERO - -0.0 and 0.0 map to 0.0

• VEC_SIGN_ZERO_TO_SIGNED_ZERO - -0.0 maps to -0.0 and 0.0 maps to 0.0

• VEC_SIGN_ZERO_TO_SIGNED_UNIT - -0.0 maps to -1.0 and 0.0 maps to 1.0
