符合ieee754标准的整数实现浮点算法，包括单精度、双精度、扩展精度（80位以及128位），来自国外。-Integer line ieee754 standard floating-point algorithms, including single-precision, double precision, extended precision (80 and 128), from abroad.

用整形进行32位及64位浮点运算，对CPU不支持浮点运算的码农特别有用。-This is a software implementation of floating-point that conforms to the IEC/IEEE Standard for Binary Floating-Point Arithmetic
