Question

what is the c++ way of saying (float)Math

Answer 1

What are you trying to say with "(float)Math"?

Answer 2

cosu=(float)Math.cos(u)
this is in java
how do i say this in c++

Answer 3

//outer loop iterates over u
u = -M_PI;
for (i = nsides - 1; i >= 0; i--) {
cosu = (float)Math.cos(u);
sinu = (float)Math.sin(u);
cosudu = (float)Math.cos(u+du);
sinudu = (float)Math.sin(u+du);

//the inner loop iterates over v
v = -M_PI / 2.0f;
for (j = rings; j >= 0; j--) {
cosv = (float)Math.cos(v);
sinv = (float)Math.sin(v);
cosvdv = (float)Math.cos(v+dv);
sinvdv = (float)Math.sin(v+dv);

Answer 4

i'm trying to convert java to c++

Answer 5

Looks like you #include <math.h> then you just use global functions sin() and cos().

Answer 6

i already have that header

Answer 7

i can't get java code to work in c++
i wish there was a program translator between the two lol

Answer 8

Did you try
sinu = sin(u);
or maybe
sinu = (float)sin(u);
I don't know all the details of math.h, but you can google it and I'm sure find lots of info. Specifically the function prototypes (parameters and return types).

Answer 9

Porting one language to another is not trivial. Writing C++ is especially not trivial. Porting something to C++ will be a challenge. Good luck!

Answer 10

thanks for thinking for me lol
i'm totally clueless about programming
its a course required for my phd
they make you take an advanced programming class and i have no experience lol

Answer 11

thank god i only have to take one computer class

Answer 12

Wow. You have to do C++ with no experience? That is...horrifying. You'll need more than luck.

Answer 13

lol
c++ with open GL

Answer 14

there is one computer science person in the class
the rest of us are pure math people

Answer 15

Well, I am absolutely positive that programming would be a good skill for any mathematician. Maybe not C++, but something like python at least.

Answer 16

maybe

Answer 17

thanks again for your help
