math - How do you round a two decimal places in Javascript? -

i trying round number 2 decemals , giving me integers!

var 4 = 10.99 + 89.78899999 total = number(a) + number(b);

here have:

math.round(total, 2); // gives me 101 need show 100.78

what trick this?

you should utilize tofixed(2) with:

alert(12.432432.tofixed(2)); // 12.43

math.round for: "returns value of number rounded nearest integer."

btw, 4 isn't valid variable name in javascript, can't begin number.

valid characters javascript variable names

javascript math decimal

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
