Operators:
+ - * / and parentheses
Constants:
Pi=PI, PiD2=Pi/2, PiD4=Pi/4, Pi2=2*Pi, e=Exp(1), e10=Exp(0.1), Deg=180/Pi
Functions:
Unless otherwise indicated, all functions take a single numeric argument, enclosed in parentheses after the name of the function.
Algebraic: Abs, Sqrt, Power(x,y)=x^y, Fact=x!, Gamma=(n-1)!
Transcendental: Exp, Ln, Log10, Log2
Trigonometric: Sin, Cos, Tan, Cot, Sec, Csc
Inverse Trig: ASin, ACos, ATan, ACot, ASec, ACsc

Inverse Hyp: ASinH, ACosH, ATanH, ACotH, ASecH, ACscH
Statistical: Norm, Gauss, Erf, ChiSq(x,df), StudT(t,df), FishF(F,df1,df2)
Inverse Stat: ANorm, AGauss, AErf, AChiSq(p,df), AStudT(p,df), AFishF(p,df1,df2)
Notes:
Use Power(a,b) instead of a^b.
Functions names are case-sensitive.
Trigonometric functions work in radians. For degrees, multiply or divide by Deg (e.g. Sin(30/Deg)=0.5, ATan(1)*Deg=45)
Fact and Gamma functions work for all real numbers.
The statistical functions Norm and StudT return 2-tail p-values (e.g. Norm(1.96)=0.05), while ChiSq and FishF return 1-tail values.
Gauss(z) returns the left integral of the normal probability function (e.g. Gauss(1.96)=0.975).
Erf returns the "error function".
