XSLP_ZERO
| 
     Description
     | 
     Absolute zero tolerance
     | 
| 
     Type
     | 
     Double
     |

     Default value
     | 
     1.0E-10

     Note
     | 
     If a value is below
     XSLP_ZERO in magnitude, then it will be regarded as zero in certain formula calculations:
      an attempt to divide by such a value will give a "divide by zero" error; an exponent of a negative number will produce a "negative number, fractional exponent" error if the exponent differs from an integer by more than XSLP_ZERO. |
