Web有时候,我们需要对数据内置的类型进行转换,数据类型的转换,一般情况下你只需要将数据类型作为函数名即可。 Python 数据类型转换可以分为两种: 隐式类型转换 - 自动完成 显式类型转换 - 需要使用类型函数来转换 隐式类型转换 在隐式类型转换中,Python 会自动将一种数据类型转换为另一种数据类型,不需要我们去干预。 以下实例中,我们对两种不同类 … maximum-width signed integer type. (typedef) intptr_t. (optional) signed integer type capable of holding a pointer to void. (typedef) uint8_t uint16_t uint32_t uint64_t. (optional) unsigned integer type with width of exactly 8, 16, 32 and 64 bits respectively. See more The implementation may define typedef names intN_t, int_fastN_t, int_leastN_t, uintN_t, uint_fastN_t, and uint_leastN_t when N is not 8, 16, 32 or 64. Typedef names of the form intN_t may only be defined if the … See more Because C++ interprets a character immediately following a string literal as a user-defined string literal, C code such as printf("%"PRId64"\n",n); is invalid C++ and requires a space before PRId64.
