javascript - Operations with numbers -

what kind of methods working integer , double numbers has protractor?

i need use round() function, can't found in api. maybe know can find it?

also have problems convert text fields number.

as far know, protractor doesn't have specific methods working numbers, retrieve number via protractor .gettext() (if it's stored in input) , apply rounding , such via standard js:

var nr = element(by.css('.number')); nr.gettext().then (function(value){          var floatvalue = parsefloat(value);       return math.round(floatvalue); })
