Convert float value to NSString

Question

Do you know how can i convert float value to nsstring value because with my code, there is an error.

My Code :

- (float)percent:(float)a :(float)b{

You need to use %f format specifier for float, not %@.

NSString *str = [NSString stringWithFormat:@"%f", myFloat];

To use specific number of digits after decimal use %.nf where n is number of digits after decimal point.

// 3 digits after decimal point
NSString *str = [NSString stringWithFormat:@"%.3f", myFloat];

Obj-C uses C printf style formatting. Please check printf man page for all other possible formatting.
