@code{vec_insert_exp} built-in functions return a vector of single- or
double-precision floating
functions return vectors representing the significands and biased
exponent values of their @code{source} arguments respectively.
Within the result vector returned by @code{vec_extract_sig}, the
@code{0x800000} bit of each vector element returned when the
function's @code{source} argument is of type @code{float} is set to 1
if the corresponding floating point value is in normalized form.
Otherwise, this bit is set to 0. When the @code{source} argument is
of type @code{double}, the @code{0x10000000000000} bit within each of
the result vector's elements is set according to the same rules.
Note that the sign of the significand is not represented in the result
returned from the @code{vec_extract_sig} function. To extract the
sign bits, use the
@code{vec_cpsgn} function, which returns a new vector within which all
of the sign bits of its second argument vector are overwritten with the
sign bits copied from the coresponding elements of its first argument
vector, and all other (non-sign) bits of the second argument vector
are copied unchanged into the result vector.
The @code{vec_insert_exp} built-in functions return a vector of
single- or double-precision floating
point values constructed by assembling the values of their
@code{significands} and @code{exponents} arguments into the
corresponding elements of the returned vector. The sign of each
corresponding elements of the returned vector.
The sign of each
element of the result is copied from the most significant bit of the
corresponding entry within the @code{significands} argument. The
corresponding entry within the @code{significands} argument.
Note that the relevant
bits of the @code{significands} argument are the same, for both integer
and floating point types.
The
significand and exponent components of each element of the result are
composed of the least significant bits of the corresponding
@code{significands} element and the least significant bits of the
@ -18181,8 +18219,8 @@ corresponding @code{exponents} element.
The @code{vec_test_data_class} built-in function returns a vector
representing the results of testing the @code{source} vector for the
condition selected by the @code{condition} argument. The
@code{condition} argument must be an unsigned integer with value not
exceeding 127. The
@code{condition} argument must be a compile-time constant integer with
value not exceeding 127. The
