Package Exports

math-foreach

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (math-foreach) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Simple Array Style Calls

 math.normalize(dataStyle2));   // rerange 0-1
 math.multiply(dataStyle2, 5)); // multiplyiesvalues by 5
 math.add(dataStyle2, 5));      // adds 2 to values
 math.median(dataStyle2));      // determines median
 math.mode(dataStyle2));        // determines mode
 math.avg(dataStyle2));         // determines average
 math.min(dataStyle2));         // determines min
 math.max(dataStyle2));         // determines max
 
 math.values(dataStyle1, 'value') // returns dataStyle2

Object Array Style Calls
