possible duplicate: nsnumberformatter rounding float values
currently, calculate scaling factor using :
cgfloat scale = cgcontextgetctm(context).a; nslog(@"scale : %f", scale); i receive floating point value : 0.124979, 0.249958, 0.499917. how can utilize roundf convert 0.125, 0.250, 0.500 respectively.
try this........
nslog(@"scale : %.3f", scale); nsstring *value = [nsstring stringwithformat:@"%.3f", thefloat]; stolen previous answer
