realFloat :: RealFloat a => a -> Builder Source #
Show a signed RealFloat
value to full precision,
using standard decimal notation for arguments whose absolute value lies
between 0.1
and 9,999,999
, and scientific notation otherwise.
Encode a signed RealFloat
according to FPFormat
and optionally requested precision.
This corresponds to the show{E,F,G}Float
operations provided by base
's Numeric module.
NOTE: The functions in base-4.12
changed the serialisation in
case of a Just 0
precision; this version of text
still provides
the serialisation as implemented in base-4.11
. The next major
version of text
will switch to the more correct base-4.12
serialisation.
