showbEFloat :: RealFloat a => Maybe Int -> a -> Builder Source #
Show a signed RealFloat
value
using scientific (exponential) notation (e.g. 2.45e2
, 1.5e-3
).
In the call
, if showbEFloat
digs valdigs
is Nothing
,
the value is shown to full precision; if digs
is
,
then at most Just
dd
digits after the decimal point are shown.

showbFFloat :: RealFloat a => Maybe Int -> a -> Builder Source #
Show a signed RealFloat
value
using standard decimal notation (e.g. 245000
, 0.0015
).
In the call
, if showbFFloat
digs valdigs
is Nothing
,
the value is shown to full precision; if digs
is
,
then at most Just
dd
digits after the decimal point are shown.
Since: 2
showbGFloat :: RealFloat a => Maybe Int -> a -> Builder Source #
Show a signed RealFloat
value
using standard decimal notation for arguments whose absolute value lies
between 0.1
and 9,999,999
, and scientific notation otherwise.
In the call
, if showbGFloat
digs valdigs
is Nothing
,
the value is shown to full precision; if digs
is
,
then at most Just
dd
digits after the decimal point are shown.

showbFFloatAlt :: RealFloat a => Maybe Int -> a -> Builder Source #
Show a signed RealFloat
value
using standard decimal notation (e.g. 245000
, 0.0015
).
This behaves as showFFloat
, except that a decimal point
is always guaranteed, even if not needed.
Since: 2
showbGFloatAlt :: RealFloat a => Maybe Int -> a -> Builder Source #
Show a signed RealFloat
value
using standard decimal notation for arguments whose absolute value lies
between 0.1
and 9,999,999
, and scientific notation otherwise.
This behaves as showFFloat
, except that a decimal point
is always guaranteed, even if not needed.

:: RealFloat a | |
=> FPFormat | What notation to use. |
-> Maybe Int | Number of decimal places to render. |
-> a | |
-> Builder |
Like formatRealFloatAltB
, except that the decimal is only shown for arguments
whose absolute value is between 0.1
and 9,999,999
.

:: RealFloat a | |
=> FPFormat | What notation to use. |
-> Maybe Int | Number of decimal places to render. |
-> Bool | Should a decimal point always be shown? |
-> a | |
-> Builder |
Converts a RealFloat
value to a Builder, specifying if a decimal point
should always be shown.
