List of usage examples for java.io DataOutputStream writeDouble
public final void writeDouble(double v) throws IOException
long using the doubleToLongBits method in class Double, and then writes that long value to the underlying output stream as an 8-byte quantity, high byte first. From source file:carnero.cgeo.cgBase.java
