我有一个号码存储在一个NSNumber我想放入的号码中long double,如下所示:

NSNumberFormatter * f = [[NSNumberFormatter alloc] init]; 

[f setNumberStyle:NSNumberFormatterDecimalStyle]; 

[f setMinimumSignificantDigits:5];

NSNumber * myNumber = [f numberFromString:@"1.1234567899"]; 

long double lnumber = mynumber;
NSLog(@"%Lf ",lnumber);
