convertToFloat() Operation for Strings

Syntax	NONE `set aFloat = aString.convertToFloat() set aFloat = convertToFloat(LITERAL)`
Semantics	Converts the lexical representation of a float (e.g. 1.2345) to a Float type. The float string is considered until a non-numeric character is found (digits, signs, E and e are considered valid numeric characters for this parameter as specified in the format). The format used is: `[white spaces][+\|-][nnnnn][.nnnnn][e\|E[+\|-]nnnn]` White spaces are any tab or space character. nnnnn may be any number of digits. If the conversion is not possible, an error message is raised (for instance: `NULL` strings).
Substitutables	`aString`	Can be any variable or object attribute having the type String.
Substitutables	`LITERAL`	String literal.
Examples	NONE `set aFloat = aString.convertToFloat();` For a UML example, refer to Type Converter Operations.
