XSLP_ZERO

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.

Description	Absolute zero tolerance
Type	Double
Default value	1.0E-10
Notes	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.
