ios - How to calculate double value upto 2 decimals, but without rounding off the digits -


i have double number e.g "12.1278", want convert number 2 decimals only, "12.12".

but, when use following code:

double d = 12.1278; nslog(@"float upto 2 decimals : %.2f", d);

the output is:

float upto 2 decimals : 12.13

i want conversion like:

float upto 2 decimals : 12.12

use nsnumberformatter roundingmode of nsnumberformatterroundfloor.

double d = 12.1278;  nsnumberformatter *formatter = [nsnumberformatter new]; [formatter setroundingmode:nsnumberformatterroundfloor]; [formatter setmaximumfractiondigits:2]; nsstring *numberstring = [formatter stringfromnumber:@(d)];  nslog(@"numberstring: %@", numberstring);

nslog output:

numberstring: 12.12
