Functions
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]
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
