Three different forms are possible for representing Results of calculation of spherical coordinates: . the form designated as EMP is similar to that used in the Ephemerides of Minor Planets, having formal precision of 0.01 minute of time in right ascension and 0.1 minute of arc in declination. Longitude, latitude, azimuth and altitude are also displayed with comparable formal precision. the form designated as Positions has enhanced formal precision. ...

... To run the <LAYER> version of the example, select: flower.htm . ... However, if the page had several layers with absolute positions, and you wanted to place another layer in a relative position to one of the existing layers, you could use inline JavaScript to calculate the value for LEFT or TOP . ... In this example, there is really no need to use inline JavaScript to position the last flower layer, since you could just let the TOP value default to its natural value, as in the other flower layers. ...
