.SH "NAME"

.SH "PARAMETERS"
.PP
\fIx\fR
.RS 4
Specifies the vector to be tested for truth\&.
.RE
.SH "DESCRIPTION"
.PP
\fBall\fR
returns true if all elements of
\fIx\fR
are true and false otherwise\&. It is functionally equivalent to:
.PP
.if n \{\
.RS 4
.\}
.nf
    bool all(bvec x)       // bvec can be bvec2, bvec3 or bvec4
    {
        bool result = true;
        int i;
        for (i = 0; i < x\&.length(); ++i)
        {
            result &= x[i];
        }
