Function to convert various numerics to bigq
with full precision.
Description
Convert a numeric, a character string representing a numeric, or various mpfr
classes to a bigq
fraction. The output has the same precision as the input.
Usage
go2bigq(x, ...)
Arguments
x |
A value of class |
... |
Parameters which could be used to modify the default behavior of |
Details
The input x
, if a list, must contain only one of the allowed classes.
Character strings which represent numbers must be of the form [+,-]X[.]Y[e,E[+,-]Z], where X, Y, and Z are strictly limited to the numerals [0:9]. None of the other character options listed are required (except of course "[+,-]Z" is disallowed unless "[e,E]" exists.)
The function formatMpfr
accepts several arguments to adjust the output character string (number of digits precision, e.g.). go2bigq
passes the ...
objects to formatMpfr
.

A bigq
object containing a vector of bigq
fractions .
