Integral formatting options.

defaultIFormat = IFormat 0 NoPadding False

int = intWith defaultIFormat

Format a Bounded Integral type like Int or Word16 into decimal ASCII digits.

import Z.Data.Builder as B
import Z.Data.Text    as T

> T.validate . B.buildBytes $ B.intWith defaultIFormat  (12345 :: Int)
"12345"
> T.validate . B.buildBytes $ B.intWith defaultIFormat{width=10, padding=RightSpacePadding} (12345 :: Int)
"12345     "
> T.validate . B.buildBytes $ B.intWith defaultIFormat{width=10, padding=ZeroPadding} (12345 :: Int)
"0000012345"

Format a Integer into decimal ASCII digits.

Format a FiniteBits Integral type into hex nibbles.

import Z.Data.Builder as B
import Z.Data.Text    as T
import Data.Word
import Data.Int

> T.validate . B.buildBytes $ B.hex (125 :: Int8)
"7d"
> T.validate . B.buildBytes $ B.hex (-1 :: Int8)
"ff"
> T.validate . B.buildBytes $ B.hex (125 :: Word16)
"007d"

The UPPERCASED version of hex.

Control the rendering of floating point numbers.

Decimal encoding of an IEEE Double.

Using standard decimal notation for arguments whose absolute value lies between 0.1 and 9,999,999, and scientific notation otherwise.

Format double-precision float using drisu3 with dragon4 fallback.

Decimal encoding of an IEEE Float.

Using standard decimal notation for arguments whose absolute value lies between 0.1 and 9,999,999, and scientific notation otherwise.

Format single-precision float using drisu3 with dragon4 fallback.

A Builder which renders a scientific number to full precision, using standard decimal notation for arguments whose absolute value lies between 0.1 and 9,999,999, and scientific notation otherwise.

Like scientific but provides rendering options.

Decimal encoding of a Double, note grisu only handles strictly positive finite numbers.

Decimal encoding of a Float, note grisu3_sp only handles strictly positive finite numbers.

Decimal digit to ASCII digit.

Hexadecimal digit to ASCII char.

Hexadecimal digit to UPPERCASED ASCII char.

Count how many decimal digits an integer has.

Internal formatting backed by C FFI, it must be used with type smaller than Word64.

We use rewrite rules to rewrite most of the integral types formatting to this function.

Internal formatting in haskell, it can be used with any bounded integral type.

Other than provide fallback for the c version, this function is also used to check the c version's formatting result.
