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 (6-4=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: Xy (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*10y (3.24e+3 = 3.24*103 = 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 ( [4-6] = 2 )
- LogX - Logarithm (Base 10, Log10x)
- LnX - Natural Logarithm (Logex)
- 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(33|11) )
- 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 )
