Method Details

parse

public static Quadruple parse(String source,
 Quadruple owner)

Parses a string containing a floating-point number and sets the fields of the owner (a Quadruple instance)
uses static arrays BUFFER_4x64_B, BUFFER_6x32_A, BUFFER_6x32_B, BUFFER_6x32_C, BUFFER_12x32

Parameters:

source - input string to parse

owner - the Quadruple instance whose fields are to set so that it has the value presented by the source

Returns:

the owner with the values of the fields modified to correspond to the value presented by the source
