¶
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. |
DESCRIPTION¶
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.
