  Turn a string of digits into a number? (Message 1 to 4 of 4)

String functions for POVray include ways to turn a numerical value into a
string. But is there a function to do the converse, turn a string of digits into
an integer? Of course there is a workaround, use a loop and multiply the value
you have by 10 with each iteration as you examine the string from left to right.
That seems awkward to me. Please tell me I missed something.

My specific task is to write a script that will parse move notation for a board
game and produce an image of the position, possibly animated.

Thanks

You want val().

http://www.povray.org/documentation/view/3.6.1/228/

val(S) Convert string S to float. Returns a float value that is represented by
the text in string S. For example val("123.45") is 123.45 as a float.

Thank you! I missed that. I don't see any way to change the subject to include
the word Solved, using a browser.

In a news group, you can't change the title of the thread. All you can 
do is change the title of your reply like I did in Thinderbird.
