it
treats them
as
ordinary doubles. The L suffix
is
supported to provide
compatibility
with
ANSI
C.
Examples
of
floating-point
constants include:
1.234;
/*
double
*/
1.0e14F;
/*
float

3.14159L;
/*

Enumeration
Constants
An enumeration constant
is
an
additional
type
of
integer
constant
that
is
not
described by
K&R.
An identifier that
is
declared
as
an
enumerator can
be used in
the
same manner
as
an
integer constant. (For more information
about enumerators,
see
Section 4.6 on page
4-8.)

String
Constants
•
K&R
C does
not
limit
the length
of
string constants; however,
TMS34010
C
limits
the
length
of
string
constants
to
255
bytes.
• All characters after
an
embedded null byte in a string constant
are
ig-
nored; in other words, the first null byte terminates the string. However,
this does
not
apply to strings used
to
initialize arrays
of
characters.
•
Identical
string
constants
are
stored
as a
single
string,
not
as
separate strings
as
in
K&
R
C.
However, this does
not
apply to strings
used
to
autoinitialize arrays
of
characters.
