How/when are list items converted to float or string in js?
Hello, can someone explain to me how to find out if a function/property returns a number or string? I am not very experienced with weak typing programming languages. So basically I don't understand when a list is converted to number or string.
I would like to numerically add two numbers. One is coming as argument from a list fed into the [js] object. The other is coming from a matrix.getcell().
If I do notparseFloatthegetcell-result (e.g. m and n) it seems to get handled as strings and the + operator just concatenates the strings.
function list()
{
a = arguments[0];
b = arguments[1]; m = matrix.getcell(0);
n = matrix.getcell(1); p = parseFloat(m); r = a + b;
s = m + n;
t = a + m;
u = a + p;
//....post results
}
yes, for numerical values from a jitter matrix you have to pareseInt() or parseFloat(); like you I only discovered this recently while debugging-- it does not seem to be documented or explained. FYI if you are parsing ints from a matrix you can also use Math.floor() which is apparently faster than parseInt()
Since a matrix cell can contain more than one number (multiple planes), you get an Array object from getcell method.
ah ok-- not immediately obvious with single-plane matrices
Ahh, thanks a lot. Accessing the array like thismatrix.getcell(0)[0]returns a number without the need of parseFloat() or something like this.
