如何在iPhone应用程序中将浮点值转换为四舍五入

问题描述

我有一个浮点值，我想四舍五入到最接近的总数，我找到了一些数学函数，但是不起作用

I have a float value i want to rounded off to nearest total i have find some math function but not working

现在潜在的利润是300.52，所以如何四舍五入

Now potential profit is 300.52 so how to roundded of this please

     float potentialprofit=otherthanCereniaAnnual*totalProfit;
     NSString*potentialProfitTitle=[NSString stringWithFormat:@"%.2f",potentialprofit];

[potentialProfit setTitle:potentialProfitTitle forState:UIControlStateNormal];

推荐答案

int result = (int)ceilf(myFloat );
int result = (int)roundf(myFloat );
int result = (int)floor(myFloat);

float result = ceilf(myFloat );
float result = roundf(myFloat );
float result = floor(myFloat);
