Syntax

             number = Strings.scanReal(string);
(number, nextIndex) = Strings.scanReal(string, startIndex=1,
                                            unsigned=false, message="");

Description

The first form, "scanReal(string)", scans "string" for a Real number with leading white space and returns the value.

The second form, "scanReal(string,startIndex,unsigned)", scans the string starting at index "startIndex", checks whether the next token is a Real literal and returns its value as a Real number, as well as the index directly after the Real number. If the optional argument "unsigned" is true, the real number shall not have a leading "+" or "-" sign.

If the required Real number with leading white space is not present in "string", an assert is triggered.

(number, nextIndex) = scanReal(string, startIndex, unsigned, message)
