Detailed Description

This function compares two real numbers and determines if they are "almost" equal, i.e.

within some relative tolerance (basically ignoring the last 2 significant digits) (see "Safe Comparisons" suggestion from http://www.lahey.com/float.htm)

Note that the numbers are added together in this routine, so overflow can result if comparing two "huge" numbers.
Use EqualRealNos (nwtc_num::equalrealnos) instead of directly calling a specific routine in the generic interface.

Parameters

[in]	renum1	the first real number to compare
[in]	renum2	the second real number to compare

Returns

.true. if and only if the numbers are almost equal
