Convert a scalar Real, Integer or Boolean expression to a String representation

Syntax

String(b_expr, minimumLength=0, leftJustified=true)
String(i_expr, minimumLength=0, leftJustified=true)
String(r_expr, significantDigits=6, minimumLength=0, leftJustified=true)
String(r_expr, format)
String(e_expr, minimumLength=0, leftJustified=true)

Description

The arguments have the following meaning (the default values of the optional arguments are shown in the left column):

Boolean b_expr	Boolean expression
Integer i_expr	Integer expression
Real r_expr	Real expression
type e_expr = enumeration(..)	Enumeration expression
Integer minimumLength = 0	Minimum length of the resulting string. If necessary, the blank character is used to fill up unused space.
Boolean leftJustified = true	if true, the converted result is left justified; if false, it is right justified in the string.
Integer significantDigits = 6	defines the number of significant digits in the result string (e.g., "12.3456", "0.0123456", "12345600", "1.23456E-10")
String format	defines the string formatting according to ANSI-C without "%" and "*" character (e.g., ".6g", "14.5e", "+6f"). In particular:      format = "[<flags>] [<width>] [.<precision>] <conversion>" with <flags> zero, one or more of "-": left adjustment of the converted number "+": number will always be printed with a sign "0": padding to the field width with leading zeros <width> Minimum field width. The converted number will be printed in a field at least this wide and wider if necessary. If the converted number has fewer characters it will be padded on the left (or the right depending on <flags>) with blanks or 0 (depending on <flags>). <precision> The number of digits to be printed after the decimal point for e, E, or f conversions, or the number of significant digits for g or G conversions. <conversion> = "e": Exponential notation using a lower case e = "E": Exponential notation using an upper case E = "f": Fixed point notation = "g": Either "e" or "f" = "G": Same as "g", but with upper case E

Examples

String(2.0)   // = "2.0"
String(true)  // = "true"
String(123, minimumLength=6, leftJustified=false)  // = "   123"
