math: DTML Math Functions

  The 'math' module provides trigonometric and other math
  functions. It is a standard Python module.

  Functions

    acos(x) -- Return the arc cosine of *x*.

    asin(x) -- Return the arc sine of *x*.

    atan(x) -- Return the arc tangent of *x*

    atan2(x, y) -- Return 'atan(y / x)'. 

    ceil(x) -- Return the ceiling of *x* as a real.

    cos(x) -- Return the cosine of *x*

    cosh(x) -- Return the hyperbolic cosine of *x*.

    exp(x) -- Return 'e**x'

    fabs(x) -- Return the absolute value of the real *x*.

    floor(x) -- Return the floor of *x* as a real.

    fmod(x, y) -- Return 'fmod(x, y)', as defined by the platform C
      library. Note that the Python expression 'x % y' may not return
      the same result.

    fexp(x) -- Return the mantissa and exponent of *x* as the pair '(m, e)'. *m*
      is a float and *e* is an integer such that 'x == m * 2**e'. If
      *x* is zero, returns '(0.0, 0)', otherwise '0.5 <= abs(m) < 1'.

    hypot(x, y) -- Return the Euclidean distance, 'sqrt(x*x + y*y)'. 

    ldexp(x, y) -- Return 'x * (2**i)'. 

    log(x) -- Return the natural logarithm of *x*.

    log10(x) -- Return the base-10 logarithm of *x*.

    modf(x) -- Return the fractional and integer parts of *x*. Both results
      carry the sign of *x*. The integer part is returned as a real.

    pow(x, y) -- Return *x* to the power of *y*.

    sin(x) -- Return the sine of *x*.

    sinh(x) -- Return the hyperbolic sine of *x*.

    sqrt(x) -- Return the square root of *x*.

    tan(x) -- Return the tangent of *x*.

    tanh(x) -- Return the hyperbolic tangent of *x*.

  Attributes

    e -- The mathematical constant *e*.

    pi -- The mathematical constant *pi*.
