Parser for mathematical expressions
val pi : float
The trigonometric constant
val deg_to_rad : float -> float
Convert a angle in degrees to radian
val logb : float -> float -> float
Log in arbitrary base. Not too good precision
val round : float -> float
Get the integer closest to x, or 'nearest integer'
val local_vars : (string, float) Hashtbl.t
Table for local variables
val bind_local_var : string -> float -> unit
Bind a local variable to a value
val fob : bool -> float
Get a floating-point 0 or 1 from a boolean
val bof : float -> bool
Get a bool from a float
val nfb : float -> float
Normalise a floating point boolean, ie get a 0 or a 1
val fxor : float -> float -> float
floating point xor logical operator
val disp_bind : string -> float -> unit
Display a binding cleanly
val display_bindings : unit -> unit
Display all bindings
