Documentation for method
base assembled from the following types:
method base(Real: Int where 2..36, ? --> Str)
Converts the number to a string, using
$base as base. For
$base larger than ten, capital Latin letters are used.
255.base(16); # 'FF'
$digits argument asks for that many digits of fraction (which may not be negative). If omitted, a reasonable default is chosen based on type. For Int this default is 0. For Num, the default is 8. For Rational, the number of places is scaled to the size of the denominator, with a minimum of 6.
A special value of
*) can be given as
$digits, which functions the same as when
$digits is not specified for all
Real types except the
Whatever indicates that you wish all of the possible digits of the fractional part, but use caution: since there's no detection of repeating fractional parts (the algorithm will eventually stop after generating 2**63 digits).
The final digit produced is always rounded.
say pi.base(10, 3); # OUTPUT: «3.142␤»say (1/128).base(10, *); # OUTPUT: «0.0078125␤»say (1/100).base(10, *); # OUTPUT: «0.01␤»say (1/3) .base(10, *); # WRONG: endlessly repeating fractional part
