showbRealFloatPrec :: RealFloat a => Int -> a -> Builder

Convert a RealFloat value to a Builder with the given precedence.

Since: 2

showbEFloat :: RealFloat a => Maybe Int -> a -> Builder

Show a signed RealFloat value using scientific (exponential) notation (e.g. 2.45e2, 1.5e-3).

In the call showbEFloat digs val, if digs is Nothing, the value is shown to full precision; if digs is Just d, then at most d digits after the decimal point are shown.

Since: 2

showbFFloat :: RealFloat a => Maybe Int -> a -> Builder

Show a signed RealFloat value using standard decimal notation (e.g. 245000, 0.0015).

In the call showbFFloat digs val, if digs is Nothing, the value is shown to full precision; if digs is Just d, then at most d digits after the decimal point are shown.

Since: 2

showbGFloat :: RealFloat a => Maybe Int -> a -> Builder

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 showbGFloat digs val, if digs is Nothing, the value is shown to full precision; if digs is Just d, then at most d digits after the decimal point are shown.

Since: 2

showbFFloatAlt :: RealFloat a => Maybe Int -> a -> Builder

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

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.

Since: 2

showbFPFormat :: FPFormat -> Builder

Convert an FPFormat value to a Builder.

Since: 2

data FPFormat

Control the rendering of floating point numbers.

Constructors

Exponent

Scientific notation (e.g. 2.3e123).

Fixed

Standard decimal notation.

Generic

Use decimal notation for values between 0.1 and 9,999,999, and scientific notation otherwise.
