Class SMath
java.lang.Object
swisseph.SMath
public class SMath
- extends java.lang.Object
Helper class containing useful mathematical functions and constants.
This class mirrors Math, but is 100% portable. Also, these algorithms are all accurate
to less than 1 ulp.
The source of the various algorithms used is the fdlibm library, at:
http://www.netlib.org/fdlibm/
Note that angles are specified in radians. Conversion functions are
provided for your convenience.
