LabVIEW编程LabVIEW开发IEEE754转换例程与相关资料 此 VI将单个精度数字转换为二进制 IEEE 754 表示，反之亦然。 LabVIEW 在四舍五入浮点编号时使用IEEE 754标准。IEEE-754 号码的值计算为：符号 * 2指数* 曼蒂萨 该标志存储在位 32 中。指数可以通过减去 127 来从位 24-31 进行计算。曼蒂萨（也称为分数）存储在位 1-23。 此 VI 提供了有关 IEEE 754 二进制值计算方式的见解。。 Convert Between IEEE 754 (Floating Point) and Binary Information - NI Community Overview This VI allows you to convert a single precision number to binary IEEE 754 representation and vice versa.
Description LabVIEW uses the IEEE 754 standard when rounding a floating point number. The value of a IEEE-754 number is computed as: sign * 2exponent * mantissa The sign is stored in bit 32. The exponent can be computed from bits 24-31 by subtracting 127. The mantissa (also known as fraction) is stored in bits 1-23. This VI provides insight on how the IEEE 754 binary value is calculated.
