The math library provides a number of useful math functions as well as special functions for Base64, and hashing and digests. More are added as needed. To make your own contributions, see the page Pico Engine welcoming your contributions for step-by-step guidance.

General Functions

absolute value

...

math:round(4066.123,2)   // 4066.12
math:round(4066.123,0)   // 4066
math:round(4066.123,-2)  // 4100

Base64 Functions

math:base64encode(str, [encoding])

Given a utf8 string, str of type [encoding], return the base64 string string. If the encoding is omitted, it defaults to utf8. 

math:base64encode(payload,"hex")

math:base64decode(str,[encoding])

Decode the given base64 string, str, return the utf8 stringstr returning a value with a type of [ encoding ] . If the encoding is omitted, it defaults to utf8. 

math:base64decode(payload,"hex")
