Overview

Function objects for testing Graph#draw_func with functions for which the precision of function evaluation is enforced. This enforced precison is set with the creation of the function object.

Instance Method Summary

• #at(x) ⇒ Object
• #initialize(n = R.prec) ⇒ Sin constructor

  A new instance of Sin.

Constructor Details

#initialize(n = R.prec) ⇒ Sin

Returns a new instance of Sin.

# File 'lib/graph.rb', line 294

def initialize(n = R.prec)
  @precMem = R.prec
  @precLoc = n
end
