Mathematical functions plugin
This plugin provides some basic mathematical functions. This plugin will always be linked statically into LCD4Linux, and therefore does not follow the plugin_name::function scheme.
Constants
The Plugin defines the following variables:
Functions:
| sqrt(x) | square root
|
| exp(x) | base-e exponential function
|
| ln(x) | natural logarithmic
|
| log(x) | base-10 logarithmic
|
| sin(x) | sine function
|
| cos(x) | cosine function
|
| tan(x) | tangent function
|
| ceil(x) | round up to next integer
|
| floor(x) | round down to next integer
|
| min(a,b) | minimum of a and b
|
| max(a,b) | maximum of a and b
|
| decode(index,...) | return parameter specified by index
|
decode() examples
| expression | result
|
| decode(-1,'a','b') | ''
|
| decode(0,'a','b') | 'a'
|
| decode(1,'a','b') | 'b'
|
| decode(2,'a','b') | ''
|
| decode(3,'a','b','c','d','e','f') | 'd'
