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.
