Question

I have strings that look about like this:

stringA = @"29.88";
stringB = @"2564";
stringC = @"12";
stringD = @"-2";

what is the best way to convert them so they can all be used in the same mathmatical formula?? that includes add, subtract.multiply,divide etc

Answer 1

Assuming that you have NSString variables.

NSString *stringA = @"29.88";
NSString *stringB = @"2564";
NSString *stringC = @"12";
NSString *stringD = @"-2";

suppose, you want to convert a string value to float value, use following statement.

float x=[stringA floatValue];

suppose, you want to convert a string value to integer value, use following statement.

NSInteger y = [stringC intValue];

Hope, it helps to you.
