isequal(3clc) Component-wise compare of x == y.
isnotequal(3clc) Component-wise compare of x != y.
isgreater(3clc) Component-wise compare of x > y.
isgreaterequal(3clc) Component-wise compare of x >= y.
isless(3clc) Component-wise compare of x < y.
islessequal(3clc) Component-wise compare of x <= y.
islessgreater(3clc) Component-wise compare of (x < y) || (x > y).
isfinite(3clc) Test for finite value.
isinf(3clc) Test for positive or negative infinity.
isnan(3clc) Test for a NaN.
isnormal(3clc) Test for a normal value.
isordered(3clc) Test if arguments are ordered.
isunordered(3clc) Test if arguments are unordered.
signbit(3clc) Test for sign bit.
any(3clc) 1 if MSB in any component of x is set; else 0.
any(3clc) 1 if MSB in all components of x is set; else 0.
bitselect(3clc) Each bit of result is corresponding bit of a if corresponding bit of c is 0.
select(3clc) For each component of a vector type, result[i] = if MSB of c[i] is set ? b[i] : a[i] For scalar type, result = c ? b : a.


If an implementation extends this specification to support IEEE-754 flags or exceptions, then all built-in relational functions shall proceed without raising the invalid floating-point exception when one or more of the operands are NaNs.
