Converting Float to Int in Python Python provides a built-in functionint()that can convert a float to an integer. This function truncates the decimal part and returns the integer part of the float. float_num=10.
y是float型，a是int型，把float变量赋给int变量通常会导致精度丢失，所以有一个warning。改成a = (int)y;强制类型转换。主函数部分改为：void main(char argc,char*argv)程序末尾：getchar();return 0;}你是初学者吧？警告：float型转换为int型

int i = Integer.parseInt(Float.toHexString(x)); 1. A NumberFormatException will be thrown because the Hex value is floating point, and your trying to convert it to an Integer, a non-floating point data type. 2. A float can't represent a 20 digit number in binary. You lose precisio...

Just changefloattodecimal(ornumeric). Internally, floats and doubles are maintained in an entirely different format from decimals and numerics. That's why you don't get the rounding (and apparently conversion) problems with decimal/numeric. ...
