Bug Report Crystal currently allows writing arbitrarily large literals for floating types: puts 2e999 # => Infinity However, the same isn't true for macro code. There, crystal uses the String#to_f* methods to parse integer literals. Sinc...

To achieve this, we iterate through each element of f_vec using a range-based for loop. Inside the loop, we perform the type conversion using a C-style cast: int(f).As we can see in the output, this cast converts the floating-point number f to its integer representation....
The _Float16 type with binary16 format can represent normalized values in the range of 2-14 to 65504.There are 11 bits of significant precision, approximately 3 decimal digits. Also subnormal values aresupported, as defined by FLT16_HAS_SUBNORM in float.h.The _Float16 type is a storage ...

1. 问题引出 最近遇到了一个小问题,即: 读取文本文件的内容,然后将文件中出现的数字(包括double, int, float等)转化为16进制0x存储 原本以为非常简单的内容,然后就着手去写了python,但是写着写着发现不对: python貌似没办法直接读取内存数据 ; 因此不得不借助于C语言
Float and double are similar types. Float is a single-precision, 32-bit floating point data type; double is a double-precision, 64-bit floating point data type. The biggest differences are in precision and range. Double: The double accommodates 15 to 16 digits, compared with float's seven...
