Objective-C Formatting CGFloat

Question

Code CGFloat a=3.45378;

I want change the result to CGFloat a=3.45f; only 2 precision

I know how printf works. but I don't know how to do this just keep 2 precision.

Answer 1

To lose the extra precision, and round to the nearest two decimals, follow these steps:

• Multiply your number by 100 : 345.378
• Round your number to the nearest integer : 345
• Divide your number by 100 : 3.45
