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{
         


        

Answer 1

[NSString stringWithFormat:@"%f", tx_nb_demande_portabilite];

Answer 2

one more option:

NSString * str = [NSNumber numberWithFloat:value].stringValue;

Answer 3

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.

Answer 4

@"%f" sounds like more appropriate format string for float.

Answer 5

A modern (and less verbose) approach would be:

NSString *str = @(myFloat).description;
