3.8 Math
Adds the given numbers left to right and returns the result. If only one argument is given,
returns the argument. If no arguments are provided, returns 0.
Subtracts the given numbers left to right and returns the result. If only one
argument is given, returns (- 0 x).
Divides the numbers from left to right and returns the result. If only one
argument is given, returns (/ 1 x).
Multiplies the numbers given from left to right and returns the result. If no
argument is given, returns one. If one argument is given, returns the argument.
Returns True if all the numbers are numerically equal.
Returns True if all arguments are greater than the one previous going right
(ie, x < y < z, etc.)
Returns True if all arguments are less than the one previous going right
(ie, x > y > z, etc.)
A bound variable containing the 64-bit floating point value of pi.
A bound variable containing the 64-bit floating point value of Euler’s number.
Returns the modulus of x divided by y.
Returns the absolute value of n.
Returns True if n is even.
Returns True if n is odd.
Returns -1 if n is negative, 0 if n is zero,
and 1 if n is positive.
Returns the value of ex.
Returns the sine of x as a floating point value.
Returns the cosine of x as a floating point value.
Returns the tangent of x as a floating point value.
Returns the value of x, rounded to a whole number, rounded down.
