Available Functions and Constants in Expressions
printf(format, ...args)
See Lua string.format.dfrac(number, is_factor)
Formats a float as a fraction, if possible. If it is a factor, then the number 1 or -1 will only produce its sign as an output, useful when formatting as a factor of pi, for example. See #Example below.sin,floor,abs,...
Any constant or function from the Lua math library can be used directly (without themath.
prefix).
