- 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*.
