Float

public Float(String str)
      throws IllegalArgumentException

Instantiates a new single-precision complex number value from the string repressentation of it in a FITS header value. By default, it will parse complex numbers as a comma-separated pair of real values enclosed in a bracket, such as (1.0, -2.0), or standard real values, such as 123.456 or 123 (as real-only values). There can be any number of spaces around the brackets, number components or the comma.

Parameters:

str - the FITS string representation of the complex value

Throws:

IllegalArgumentException - if the supplied string does not appear to be a FITS standard representation of a complex value.
