All together, Equalizer has 54 Functions, Operators and Constants.



Operators

 
Operators come between two expressions. Equalizer supports
these operators:
 X + Y  add: sum of X and Y
 X  Y  subtract: difference of X from Y (64=2)
 X * Y  multiply: X times Y (2*3=6)
 X / Y  divide: X's in Y (14/4=3.5)
 X % Y  percents: X percent out of Y (15%20=3)
 X ^ Y  power: X^{y} (2^3=8)
 X div Y  whole Y's in X (10 div 3 = 3)
 X mod Y  X in module Y (10 mod 3 = 1)
 X t Y  base X square of Y (3 t 8=2)
 X e± Y  exponent: X*10^{y} (3.24e+3 = 3.24*10^{3} = 3240)



Constants

 
Use a constant in the same way you'd use any number:
 pi = π ≈ 3.1415926535897
 phi = φ ≈ 1.6180339887498
 e ≈ 2.71828182845905
Note: e+ and e are used for exponents.
 x  in future versions, x will be used to draw a graph of the function.



Functions

 
Functions come before or after expressions. Equalizer
supports these functions:
 tX  Square Root (t9=3)
 [x]  Absolute Value ( [46] = 2 )
 LogX  Logarithm (Base 10, Log_{10}x)
 LnX  Natural Logarithm (Log_{e}x)
 FixX  The whole part of a number ( fix(3.9)= 3, fix(2.8)= 2 )
 IntX  The integer that is smaller than x, or equal to it
( int(1.9)= 1, int(1.1)= 2 )
 RoundX  Nearest integer ( round(1.2)= 1, round(1.9)= 2)



Functions: Trigonometry

 
 Sinα Sine of the angle
For All Trigonometry Functions:
 ASinα Arc (invert) Sine
 SinHα Hyperbolic Sine
 ASinHα Arc Hyperbolic Sine
 Cosα  Cosine of the angle
 Tanα  Tangent of the angle
 Cotα  Cotangent of the angle
 Secα  Secant
 Cscα  Cosecant
 *Note: All Trigonometry functions are in Radians
 Radα  Convert a degree angle to radians
 Degα  Convert a radian angle to degrees



Functions: Combinatorics

 
 X!  Factorial (4! = 1*2*3*4 = 24)
 C(n,m)  The number of ways to chose M items from a group of N. (C(4,2)=6)
 P(n,m)  The number of ways to chose and order M items from a group of N. (P(4,2)=12)



Functions: Statistics

 
These functions work on a series of numbers, and must
be written with brackets. (use comma "," to seperate the items, or 'pipe' if comma
is your decimal seperator, e.g. Max(3,5) or Sum(3311) )
 Max( X1,X2,X3...)  The maximum number of the series ( max(5,2,3+1) = 4 )
 Min( X1,X2,X3...)  The minimum number of the series ( min(5,2,3+1) = 5 )
 Sum( X1,X2,X3...)  The sum of all number ( sum(5,2,3+1) = 1 )
 Avg( X1,X2,X3...)  The average of all number ( avg(10,2,9) = 7 )
