|Description: The 'greater than'
relation is merely the converse of the 'less than or
equal to' relation defined by df-lt 8766. Defined in ISO 80000-2:2009(E)
operation 2-7.12. See df-gte 28446 for a discussion on why this approach is
used for the definition. See gt-lt 28449 and gt-lth 28451 for more conventional
expression of the relationship between and .
As a stylistic issue, set.mm prefers 'less than or equal' instead of
'greater than or equal' to reduce the number of conversion steps. Thus,
we discourage its use, but include its definition so that there is
formal definition of this symbol.
