Types for text mangling.

Documentation

data Format

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.

newtype Fast a

Render a floating point number using a much faster algorithm than the default (up to 10x faster). This performance comes with a potential cost in readability, as the faster algorithm can produce strings that are longer than the default algorithm (e.g. "1.3300000000000001" instead of "1.33").
