$FN[UMBER] ( numexpr , fncodexpr )
See 2.2.4 for the definition of numexpr.
| fncodexpr | ::= | expr | V | fncode |
See 2.3 for the definition of expr. See section 1 for the definition of V.
| fncode | ::= | fncodatom ... |
| fncodatom | ::= | │ │ │ │ │ |
P T , + - |
│ │ │ │ │ |
(Note: comma) (Note: hyphen) |
returns a value which is an edited form of numexpr. Each fncodatom is applied to numexpr in formatting the results by the following rules (order of processing is not significant):
| fncodatom | Action |
|---|---|
| P | Represent negative numexpr values in parentheses. Let A be the absolute value of numexpr. Use of fncode "P" will result in the following: |
| T | Represent numexpr with a trailing rather than a leading "+" or "-" sign. Note: if sign suppression is in force (either by default on positive values, or by design using the "-" fncodatom), use of fncode "T" will result in a trailing space character. |
| , | Insert comma delimiters every third position to the left of the decimal (present or assumed) within numexpr. Note: no comma shall be inserted which would result in a leading comma character. |
| + | Force a plus sign ("+") on positive values of numexpr. Position of the "+" (leading or trailing) is dependent on whether or not fncodatom of "T" is specified. |
| - | Suppress the negative sign "-" on negative values of numexpr. |
If fncodexpr equals an empty string, no special formatting is performed and the result of the expression is the original value of numexpr.
More than one occurrence of a particular fncodatom within a single fncode is identical to a single occurrence of that fncodatom. Erroneous conditions are produced when a fncodatom "P" is present with any of the sign suppression or sign placement fncodatoms ("T+-").
$FN[UMBER] ( numexpr , fncodexpr , intexpr )
See 2.2.4 for the definition of numexpr. See 2.2.4.1 for the definition of intexpr.
This form is identical to the two-argument form of $FN, except that numexpr is rounded to intexpr fraction digits, including possible trailing zeros, before processing any fncodatoms. If intexpr is zero, the evaluated numexpr contains no decimal point. Note: if (–1 < numexpr < 1), the result of $FN has a leading zero ("0") to the left of the decimal point.
