PractiCalc maintains a variety of optimized built-in (intrinsic) functions. All the intrisic functions can be freely used in your equations and user-defined formula.
The built-in functions are grouped into function families:
Constants - these are zero argument functions. Examples are pi, e and c (sped of light in a vacuum).
Limits - functions that provide boundary conditions for arguments. Examples are abs, trunc, max and min. Also in this group are the bin, oct and hex to decimal converters.
Arithmetic - simple function prividing pow, rand, sq, sqrt, log and a special series function.
Statictical - functions that operate on lists of numbers. These functions include: sum,prod,mean,stdev.
Trigonometric - functions in the family of sin, acos, Included are radian, degree, gradient and sexagesimal converters.
Hyperbolic - functions
Financial - a small number of financial calculators for PV, FV etc.
Conditional iif function
Other - a variety of more exotic but useful functions, e.g. Prime, IsPrime, Bessel,
Example of the use of built-in functions:
-2.25 * max ( 2.37 , e, log ( c ) ) ^ -1.25
