Returns a string representation of the BigFloat.
toString(radix?)
radix optional
Specifies a radix for converting value to string.
A string representing the BigFloat value.
If the radix is a power of two, the conversion is done with infinite precision.
Otherwise, the number is rounded to nearest with ties to even using the global precision. It is then converted to string using the minimum number of digits so that its conversion back to a floating point using the global precision and round to nearest gives the same number.
The exponent letter is e for base 10, p for bases 2, 8, 16 with a binary exponent, and @ for the other bases.
