NAME
|
|
base - set default output base
|
|
|
|
SYNOPSIS
|
|
base([mode])
|
|
|
|
TYPES
|
|
mode real
|
|
|
|
return real
|
|
|
|
DESCRIPTION
|
|
The base function allows one to specify how numbers should be
|
|
printed. The base function provides a numeric shorthand to the
|
|
config("mode") interface. With no args, base() will return the
|
|
current mode. With 1 arg, base(val) will set the mode according to
|
|
the arg and return the previous mode.
|
|
|
|
The following convention is used to declare modes:
|
|
|
|
base config
|
|
value string
|
|
|
|
2 "binary" binary fractions
|
|
8 "octal" octal fractions
|
|
10 "real" decimal floating point
|
|
16 "hex" hexadecimal fractions
|
|
-10 "int" decimal integer
|
|
1/3 "frac" decimal fractions
|
|
1e20 "exp" decimal exponential
|
|
|
|
For convenience, any non-integer value is assumed to mean "frac",
|
|
and any integer >= 2^64 is assumed to mean "exp".
