Operations on objects
val copy : (< .. > as 'a) -> 'a
Oo.copy o returns a copy of object o , that is a fresh object with the same methods and instance variables as o
val id : < .. > -> int
Return an integer identifying this object, unique for the current execution of the program.

Module Complex

Complex numbers.
This module provides arithmetic operations on complex numbers. Complex numbers are represented by their real and imaginary parts (carte-
sian representation). Each part is represented by a double-precision floating-point number (type float ).
type t = {
re : float ;
im : float ;
}
The type of complex numbers. re is the real part and im the imaginary part.
val zero : t
The complex number 0 .
val one : t
The complex number 1 .
val i : t
The complex number i .
val neg : t -> t
Unary negation.
val conj : t -> t
Conjugate: given the complex x + i.y , returns x - i.y .
val add : t -> t -> t
Addition
val sub : t -> t -> t
Subtraction
val mul : t -> t -> t
Multiplication
val inv : t -> t
Multiplicative inverse ( 1/z ).
val div : t -> t -> t
Division
val sqrt : t -> t
Square root. The result x + i.y is such that x > 0 or x = 0 and y >= 0 . This function has a discontinuity along the negative real axis.
val norm2 : t -> float
Norm squared: given x + i.y , returns x^2 + y^2 .
val norm : t -> float
Norm: given x + i.y , returns sqrt(x^2 + y^2) .
val arg : t -> float
Argument. The argument of a complex number is the angle in the complex plane between the positive real axis and a line passing through
zero and the number. This angle ranges from -pi to pi . This function has a discontinuity along the negative real axis.
val polar : float -> float -> t
polar norm arg returns the complex having norm norm and argument arg .
val exp : t -> t
Exponentiation. exp z returns e to the z power.
val log : t -> t
Natural logarithm (in base e ).
val pow : t -> t -> t
Power function. pow z1 z2 returns z1 to the z2 power.
