Syntax

epsm
epsm(units)

Description

epsm is the limit of map angular precision. It is useful in avoiding trigonometric singularities, among other things.

epsm(units) returns the same angle in units corresponding to any valid angle units string. The default is 'degrees'.

Examples

The value of epsm is 10^-6 degrees. To put this in perspective, in terms of an angular arc length, the distance is:

epsmkm = deg2km(epsm)
epsmkm =
   1.1119e-04      % kilometers

This is about 11 centimeters, a very small distance on a global scale.
