format() MATH/String menu
format(
expression
[
, formatString
]
) ⇒
string
Returns
expression
as a character string based on
the format template.
expression
must simplify to a number.
formatString
is
a string and must be in the form: “
F
[
n
]
”, “
S[
n
]
”,
“
E[
n
]
”, “
G[
n
][
c
]
”, where
[ ]
indicate optional portions.
F[
n
]
: Fixed format.
n
is the number of digits to
display after the decimal point.
S[
n
]
: Scientific format.
n
is the number of digits to
display after the decimal point.
E[
n
]
: Engineering format.
n
is the number of digits
after the first significant digit. The exponent is
adjusted to a multiple of three, and the decimal point
is moved to the right by zero, one, or two digits.

c
]
: Same as fixed format but also separates
digits to the left of the radix into groups of three.
c
specifies the group separator character and defaults
to a comma. If
c
is a period, the radix will be shown
as a comma.
[R
c
]
: Any of the above specifiers may be suffixed
with the
R
c
radix flag, where
c
is a single character
that specifies what to substitute for the radix point.

Returns the fractional part of the argument.
For a list or matrix, returns the fractional parts of the
elements.
The argument can be a real or a complex number.
