原标题:NSNumberFormatter to format currency not working for floats

使用NSNumberFormatter作为货币格式的Im,但格式不使用浮动。 然而,当我使用双倍时,它就发挥了作用。 我们需要与浮体合作,因为我不需要双倍工作。

float t1 = 999999.99;
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[formatter setAllowsFloats:YES];
[formatter setMaximumFractionDigits:2];
[formatter setAlwaysShowsDecimalSeparator:YES];
[formatter setGeneratesDecimalNumbers:YES];
NSString *formattedOutput = [formatter stringFromNumber:[NSNumber numberWithFloat:t1]];
NSLog(@"Output as currency: %@", formattedOutput);

this outputs - Output as currency: $1,000,000.00 and not as $9,99,999.99

事先感谢您的帮助。

为了避免与浮标(和两倍)发生四舍五入,因为你应当使用NSDecimalNumber。 你在问询中列举的所有现行法典都与他们合作。 只是抽出你的浮体,而是使用以下线:

NSDecimalNumber *t1 = [NSDecimalNumber decimalNumberWithString:@"999999.99"];

(请注意,根据您的变数,还有其他办法可创造国家抽样调查。)
