float32和float64的区别 - CSDN文库
WebJun 9, 2024 · It's not a dumb question at all, but the answer is complicated, and depends on how you're going to use the information. For example, the IEEE 754 binary64 type can faithfully represent any not-too-large not-too-small decimal value with 15 or fewer significant digits, but to represent a binary64 value faithfully in decimal requires 17 decimal digits. . … Web1 day ago · 15. Floating Point Arithmetic: Issues and Limitations ¶. Floating-point numbers are represented in computer hardware as base 2 (binary) fractions. For example, the decimal fraction 0.125 has value 1/10 + 2/100 + 5/1000, and in the same way the binary fraction 0.001 has value 0/2 + 0/4 + 1/8. These two fractions have identical values, the … Web用float32存储中间变量. 计算过程中的中间变量要用float32来存储。比如MaxPool2d在channels last上的kernel,每个thread需要申请一个长度为‘channels’的临时buffer,用于存储计算max过程中的临时结果。这 … earth day puns
