Owning Palette: String/Number Conversion Functions

Requires: Base Package

Converts number to an F-format (fractional notation), floating-point string at least width characters wide or wider if necessary.

The connector pane displays the default data types for this polymorphic function.

use system decimal point defines the decimal separator. If TRUE (default), the decimal separator uses the localized decimal separator. If FALSE, the decimal separator is a period.

number can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.

width must be numeric. If unwired, the function uses exactly as many digits as are needed to represent the number, with no extra padding.

precision must be numeric. The function rounds the number of digits after the decimal point of the output string to precision.

F-format string is the resulting fractional string. F-format string can be Inf, -Inf, or NaN if the value you wire to number is infinity or is not a number. The following table shows how the values of number, width, and precision affect F-format string. In this table, the underline character ( _ ) represents a space in F-format string.

number	width	precision	F-format string	Comments
4.911	6	2	_ _4.91	number is rounded, padded with spaces on the left.
.003926	8	4	_ _0.0039	number is rounded, padded with spaces on the left.
–287.3	5	0	_–287	number is rounded, padded with spaces on the left.
