Relational Built-In Functions

Click an item in the table below for details about that function.

isequal

Component-wise compare of x == y.

isnotequal

Component-wise compare of x != y.

isgreater

Component-wise compare of x > y.

isgreaterequal

Component-wise compare of x >= y.

isless

Component-wise compare of x < y.

islessequal

Component-wise compare of x <= y.

islessgreater

Component-wise compare of (x < y) || (x > y).

isfinite

Test for finite value.

isinf

Test for positive or negative infinity.

isnan

Test for a NaN.

isnormal

Test for a normal value.

isordered

Test if arguments are ordered.

isunordered

Test if arguments are unordered.

signbit

Test for sign bit.

any

1 if MSB in any component of x is set; else 0.

all

1 if MSB in all components of x is set; else 0.

bitselect

Each bit of result is corresponding bit of a if corresponding bit of c is 0.

select

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.
