| Extended Precision | x: _ _ _ | Num/Denom |
|
x: applies to real numbers and produces extended precision
rational numbers. It applies to integers and produces extended integers.
The implied comparison in x: is tolerant.
The inverse x:^:_1 converts rationals, including extended integers,
into finite precision numbers (floating point or integer).
|
1 x: y is the same as x: y ;
and 2 x: y produces the two extended integers of the numerator
and denominator of the argument.
