### `gte?` ###

`gte?` evaluates both of its arguments to numbers, then evaluates to `#t`
if the first number is greater than or equal to the second.

    | (gte? 6 4)
    = #t

    | (gte? 6 8)
    = #f

    | (gte? 6 6)
    = #t

    | (gte? 1610612736 (subtract 0 1610612736)))
    = #t

    | (gte? (subtract 0 1610612736) 1610612736)
    = #f

`gte?` expects exactly two arguments, both numbers.

    | (gte? 14)
    ? abort (illegal-arguments

    | (gte? 14 23 57)
    ? abort (illegal-arguments

    | (gte? 14 #t)
    ? abort (expected-number #t)

    | (gte? #t 51)
    ? abort (expected-number #t)
