acos :: Double -> Double Source

The acos function computes the principal value of the arc cosine of x in the range [0, pi]

c_acos :: CDouble -> CDouble Source

asin :: Double -> Double Source

The asin function computes the principal value of the arc sine of x in the range [-pi2, +pi2].

c_asin :: CDouble -> CDouble Source

atan :: Double -> Double Source

The atan function computes the principal value of the arc tangent of x in the range [-pi2, +pi2].

c_atan :: CDouble -> CDouble Source

atan2 :: Double -> Double -> Double Source

The atan2 function computes the principal value of the arc tangent of y/x, using the signs of both arguments to determine the quadrant of the return value.

c_atan2 :: CDouble -> CDouble -> CDouble Source

cos :: Double -> Double Source

The cos function computes the cosine of x (measured in radians). A large magnitude argument may yield a result with little or no significance. For a discussion of error due to roundoff, see math(3).

c_cos :: CDouble -> CDouble Source

sin :: Double -> Double Source

The sin function computes the sine of x (measured in radians). A large magnitude argument may yield a result with little or no significance. For a discussion of error due to roundoff, see math(3).

c_sin :: CDouble -> CDouble Source

tan :: Double -> Double Source

The tan function computes the tangent of x (measured in radians). A large magnitude argument may yield a result with little or no significance. For a discussion of error due to roundoff, see math(3).

c_tan :: CDouble -> CDouble Source

cosh :: Double -> Double Source

The cosh function computes the hyperbolic cosine of x.

c_cosh :: CDouble -> CDouble Source

sinh :: Double -> Double Source

The sinh function computes the hyperbolic sine of x.

c_sinh :: CDouble -> CDouble Source

tanh :: Double -> Double Source

c_tanh :: CDouble -> CDouble Source

exp :: Double -> Double Source

The exp() function computes the exponential value of the given argument x.

c_exp :: CDouble -> CDouble Source

frexp :: Double -> (Double, Int)Source

frexp convert floating-point number to fractional and integral components frexp is not defined in the Haskell 98 report.

c_frexp :: CDouble -> Ptr CInt -> IO Double Source

ldexp :: Double -> Int -> Double Source

The ldexp function multiplies a floating-point number by an integral power of 2. ldexp is not defined in the Haskell 98 report.

c_ldexp :: CDouble -> CInt -> Double Source

log :: Double -> Double Source

The log() function computes the value of the natural logarithm of argument x.

c_log :: CDouble -> CDouble Source

log10 :: Double -> Double Source

The log10 function computes the value of the logarithm of argument x to base 10. log10 is not defined in the Haskell 98 report.

c_log10 :: CDouble -> CDouble Source

modf :: Double -> (Double, Double)Source

The modf function breaks the argument value into integral and fractional parts, each of which has the same sign as the argument. modf is not defined in the Haskell 98 report.

c_modf :: CDouble -> Ptr CDouble -> IO CDouble Source

pow :: Double -> Double -> Double Source

The pow function computes the value of x to the exponent y.

c_pow :: CDouble -> CDouble -> CDouble Source

sqrt :: Double -> Double Source

The sqrt function computes the non-negative square root of x.

c_sqrt :: CDouble -> CDouble Source

ceil :: Double -> Double Source

The ceil function returns the smallest integral value greater than or equal to x.
