Cast

The Cast functions are used for pilight specific casts between variable types.

Warning

The cast library was created to be backwards compatible with the event parser, but is a possible candidate to be made obsolete in the future.

boolean pilight.cast.toboolean(number | string variable)

Casts a string or number to boolean

Note

Compared to default Lua

Casting to boolean is not supported in lua

number pilight.cast.tonumber(number | boolean variable)

Casts a boolean or number to boolean

tonumber('') == nil; pilight.cast.tonumber('') == 0
tonumber('false') == nil; pilight.cast.tonumber('false') == 0
tonumber(false) == nil; pilight.cast.tonumber(false) == 0
tonumber(true) == nil; pilight.cast.tonumber(true) == 1

string pilight.cast.tostring(number | boolean variable)

Casts a string or boolean to boolean

tostring(10) == '10'; pilight.cast.tostring(10) == '10.000000'
tostring(10.0) == '10'; pilight.cast.tostring(10.0) == '10.000000'
