Convert
Data, Numeric-to-String
nmexp
is
evaluated as
a doabie-pirscislop nyrnoer-
fractional
component
in
nmexp
Is
truncaled.
These
functions
change
a
number
to a
"string." Actually the byte values
which
make
up
the
number
are
not
changed; only one
byte, the internal
data-type
specifier,
is
changed, so that
numeric
data
can be placed
in
a string variable.
That
is:
mkds
returns
an
eight-byte string.
mki$
returns a
two-byte
string.
mks$ returns
a four-byte
string.
Examples
LSET TALLY$=MKI$(I%)
Field
name tallys would
now
contain a
two-byte representation
of
the
integer i%.
A*=MKI*(8/I>
