setWord :: Word64 -> BF -> IO () Source #

Assign from a word

setInt :: Int64 -> BF -> IO () Source #

Assign from an int

setDouble :: Double -> BF -> IO () Source #

Assign from a double

setInteger :: Integer -> BF -> IO () Source #

Set an integer. If the integer is larger than the primitive types, this does repreated Int64 additions and multiplications.

setBF Source #

Arguments

:: BF
-> BF	This number is changed
-> IO ()

Assign from another number.

setString :: Int -> BFOpts -> String -> BF -> IO (Status, Int, Bool) Source #

Set the value to the float parsed out of the given string. * The radix should not exceed maxRadix. * Sets the number to NaN on failure. * Assumes that characters are encoded with a single byte each. * Retruns: - Status for the conversion - How many bytes we consumed - Did we consume the whole input

Queries and Comparisons

cmpEq :: BF -> BF -> IO Bool Source #

Check if the two numbers are equal.

cmpLT :: BF -> BF -> IO Bool Source #

Check if the first number is strictly less than the second.

cmpLEQ :: BF -> BF -> IO Bool Source #

Check if the first number is less than, or equal to, the second.

cmpAbs :: BF -> BF -> IO Ordering Source #

Compare the absolute values of the two numbers. See also cmp.

cmp :: BF -> BF -> IO Ordering Source #

Compare the two numbers. The special values are ordered like this:

-0 < 0
NaN == NaN
NaN is larger than all other numbers

getSign :: BF -> IO (Maybe Sign) Source #

Returns Nothing for NaN.

getExp :: BF -> IO (Maybe Int64) Source #

Get the exponent of the number. Returns Nothing for inifinity, zero and NaN.

isFinite :: BF -> IO Bool Source #

Check if the number is "normal", i.e. (not infinite or NaN)

isInf :: BF -> IO Bool Source #

Check if the given numer is infinite.

isNaN :: BF -> IO Bool Source #

Check if the number is NaN

isZero :: BF -> IO Bool Source #

Check if the given number is a zero.
