|
| |
| '''math.acos (x)'''
| |
|
| |
|
| |
| Returns the arc cosine of x (in radians).
| |
|

| |
|
| |
|
| |
| '''math.atan2 (y, x)'''
| |
|
| |
|
| |
| Returns the arc tangent of y/x (in radians), but uses the signs of both parameters to find the quadrant of the result. (It also handles correctly the case of x being zero.)
| |
|
| |
|
| |
| '''math.ceil (x)'''
| |
|
| |
|
| |
| Returns the smallest integer larger than or equal to x.
| |

| '''math.cos (x)'''
| |
|
| |
| Returns the cosine of x (assumed to be in radians).
| |
|
| |
|
| |
| '''math.cosh (x)'''
| |
|
| |
|
| |
| Returns the hyperbolic cosine of x.
| |
|
| |
|
| |
| ''''math.deg (x)'''
| |
|
| |
|
| |
| Returns the angle x (given in radians) in degrees.
| |
|
| |
|
| |
| '''math.exp (x)'''
| |
|
| |
|
| |
| Returns the the value ex.
| |
|
| |
|
| |
| '''math.floor (x)'''
| |
|
| |
|
| |
| Returns the largest integer smaller than or equal to x.
| |
|
| |
|
| |
| '''math.fmod (x, y)'''
| |
|
| |
|
| |
| Returns the remainder of the division of x by y.
| |
|
| |
|
| |
| '''math.frexp (x)'''
| |
|
| |
|
| |
| Returns m and e such that x = m2e, e is an integer and the absolute value of m is in the range [0.5, 1) (or zero when x is zero).
| |
|
| |
|
| |
| '''math.huge'''
| |
|
| |
|
| |
| The value HUGE_VAL, a value larger than or equal to any other numerical value.
| |
|
| |
|
| |
| '''math.ldexp (m, e)'''
| |
|
| |
|
| |
| Returns m2e (e should be an integer).
| |
|
| |
|
| |
| '''math.log (x)'''
| |
|
| |
|
| |
| Returns the natural logarithm of x.
| |
|
| |
|
| |
| '''math.log10 (x)'''
| |
|
| |
|
| |
| Returns the base-10 logarithm of x.
| |
|
| |
|
| |
| '''math.max (x, ···)'''
| |
|
| |
|
| |
| Returns the maximum value among its arguments.
| |
|
| |
|
| |
| '''math.min (x, ···)'''
| |
|
| |
|
| |
| Returns the minimum value among its arguments.
| |
|
| |
|
| |
| '''math.modf (x)'''
| |
|
| |
|
| |
| Returns two numbers, the integral part of x and the fractional part of x.
| |
|
| |
|
| |
| '''math.pi'''
| |
|
| |
|
| |
| The value of pi.
| |
|
| |
|
| |
| '''math.pow (x, y)'''
| |
|
| |
|
| |
| Returns xy. (You can also use the expression x^y to compute this value.)
| |
|
| |
|
| |
| '''math.rad (x)'''
| |
|
| |
|
| |
| Returns the angle x (given in degrees) in radians.
| |
|
| |
|
| |
| '''math.random ([m [, n]])'''
| |
|
| |
|
| |
| This function is an interface to the simple pseudo-random generator function rand provided by ANSI C. (No guarantees can be given for its statistical properties.)
| |
|
| |
| When called without arguments, returns a pseudo-random real number in the range [0,1). When called with a number m, math.random returns a pseudo-random integer in the range [1, m]. When called with two numbers m and n, math.random returns a pseudo-random integer in the range [m, n].
| |
|
| |
|
| |
| '''math.randomseed (x)'''
| |
|
| |
|
| |
| Sets x as the "seed" for the pseudo-random generator: equal seeds produce equal sequences of numbers.
