When writing out measurement equations in Seamly, there are many mathematical functions that one may use to make them work seamlessly. This is [to be] a list of the functions, with a one-line example of how to actually use them in equations. Functions are served by the muparser math library.[1]
![The Functions table in the Measurement Dialog is an excellent place to find most of the available algebraic functions of Seamly.](http://static.miraheze.org/seamlywiki/thumb/c/c9/MeasurementDialogFunctionsTable.png/300px-MeasurementDialogFunctionsTable.png)
Basic Functions
These are functions which are so basic that they didn't get included in the list
+ plus (3+4=7)
- minus (3-4=-1)
* times (3*4=12)
/ dividedby (3/4=.75)
^ to the power of (3^4=81)
Advanced Functions
Most of these functions are found in the table, however there are several which depend on your ability to construct an IF function in Seamly. As such, I will discuss the IF statement, (which is not in the list,) first, & then proceed in alphabetical order as the functions appear in the list. It may be better to list them by branch of mathematics, but for now the list, & thus the alphabet, has priority.
IF function
- if a<b then c else d looks like ( a<b ? c : d) in Seamly2D formulas.
- if e<f then f else g looks like (e<f ? f : g)
- When d is another test, then it looks like: ( a<b ? c : (e<f ? f : g) )[2]
abs - absolute value
abs(3-4)=1[3]
acos - arcus cosine function working with radians
Use: acos(N) where -1≤N≤1
acosD - arcus cosine function working with degrees
Use: acosD(N) where -1≤N≤1
acosh - hyperbolic arcus cosine function
Use: acosh(N) where N≥1
asin - arcus sine function working with radians
Use: asin(N) where -1≤N≤1
asinD - arcus sine function working with degrees
Use: asinD(N) where -1≤N≤1
asinh - hyperbolic arcus sine function
Use: asinh(N)
atan - arcus tangens function working with radians
Use: atan(N)
atanD - arcus tangens function working with degrees
Use: atanD(N)
atanh - hyperbolic arcur tangens function
Use: atanh(N) where -1<N<1
avg - (average,) mean value of all arguments
Use: avg(N1;(N2)) this does seem to be limited to two variables.
cos - cosine function working with radians
Use: cos(N)
cosD - cosine function working with degrees
Use: cosD(N)
cosh - hyperbolic cosine
Use: cosh(N)
degTorad - converts degrees to radian
Use: degTorad(N)
exp - e raised to the power of x
Use:
