Description

Write a floating point value to a Builder.

Synopsis

data FPFormat
- = Exponent
- | Fixed
- | Generic
realFloat :: RealFloat a => a -> Builder
formatRealFloat :: RealFloat a => FPFormat -> Maybe Int -> a -> Builder

Documentation

data FPFormat Source #

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.
