c - How to loop and increase by 0.01 everytime? -


i'm confused on code.

here's want do: start "v" value of 5, carry out rest of functions/calculations, increase "v" value 0.01, carry out functions/calculations, increase "v" value 0.01 again, carry out functions...do 500 times or until "v" value of 10.00 reached, whichever easier code.

here code @ moment:

//start loop on v   for(iv=5;iv<=500;iv++) {       v=0.01*iv;     //lots , lots of calculations v here } 

here get: tried setting iv<=10 10 loops test first before leaving on night. did 6 loops, starting @ v=0.05 , ending @ 0.1. problem a) didn't run 10 loops, b) didn't start @ 5.00, started @ 0.05.

any appreciated.

edit: holy crap, many answers! i've tried 2 different answers far, both work! i've been staring @ , changing code around 3 hours, can't believe easy.

you need start @ iv = 500. , if want 10 loops, , iv++ update, stop before 510.

reason: v = 0.01*iv, v = 5 means iv = 5/0.01 = 500. number of iterations, if loop of form for (x = n; x < m; x++) (constant n , m), max(0, m-n) loops executed, if x not changed in loop , no weird stuff (e.g. overflow, hidden casts of negative numbers unsigned, etc.) occurs.

edit

instead of using v = 0.01 * iv, v = iv / 100.0 more accurate. reason: 0.01 not representable in floating point, 100.0 is.
