I want to compute the points of a regular polygon in a loop:
float r = 1.0;
for (uint k=0; k < numVerts; k++) {
vertlist ~= Vec2D(r * cos(k/n * 2 * PI), ...)
}
How do I make sure k/n is a float or double?
uint is promoted to float/double with a binary math operation. You could
simply reverse the order of your expression:
2 * PI * k/n
But if you want to force a type change with simple conversions such as
these, just use a constructor:
float(k) / n * 2 * PI
There is no need to cast or use `to` (though both of those would be
equivalent to simple conversion).
