dA =    0.000
Simulate Error Conditions ...
=============================
Divide by zero:  ( 1/0.0) = Infinity
Divide by zero:  (-1/0.0) = -Infinity
  Not a number: (0.0/0.0) =      NaN

Variables that store error conditions ...
=========================================
dB = 1.0/dA = Infinity
dC =  dA/dA =      NaN

Test for variable values containing error conditions ...
========================================================
***  dB is equal to +Infinity
***  dB is not equal to -Infinity
***  dB is a Number

Evaluate y(x) for range of x values
===================================
 dX =  1.0   y(dX) =    1.500
 dX =  1.5   y(dX) =    0.667
 dX =  2.0   y(dX) = Infinity
 dX =  2.5   y(dX) =    6.000
 dX =  3.0   y(dX) = -Infinity
 dX =  3.5   y(dX) =    0.667
 dX =  4.0   y(dX) =      NaN
 dX =  4.5   y(dX) =    1.733
 dX =  5.0   y(dX) =    1.833
