String functions --- detailed description and implementation of the atof () function (full version), --- detailed description of the atof Function Atof () function Atof (): double atof (const char * str ); Function: converts a string to a floating point number. Str: string t

Header files: #include The function atof () is used to convert a string to a double-precision floating-point number (double) whose prototype is:Double atof (const char* str);The name of Atof () is derived from the abbreviation of the ASCII to floating point numbers, which scans the parameter str string, skips the preceding whitespace characters (such as spaces, t

Atof function for converting a string argument to a floating-point type/* system:linux Self-implemented atof function, the main function is used to determine the legalization of parameters, if the law calls the sub-function, or exit This program contains two algorithms atof implementation, are valid */#include Summarize:Seemingly small functions, realized quite

Atof () function Atof (): Double atof (const char * Str ); Function: converts a string to a floating point number. STR: string to be converted. Return Value: double value returned for each function. This value is generated by parsing the input character as a number. If the input cannot be converted to a value of this type, the return value is 0.0. Funct

[Arrangement] when reading files by functions such as atoi and ITOA in the Linux kernel, if we want to get the int type, such Read from "/sys/devices/platform/LCD-backlight/LEDs/LCD-backlight/brightness", obviously we want to be int type However, when calling the read system, the char type is read from the file stream. Therefore, it must be converted to an int type after reading the data. This requires atoi. Be sure to include the header file # include Here are the usage of atoi and

The four functions that are called in this article are as follows: Atoi function: Converting a string to an int type variable ATOL function: Converting a string to a long type variable Atoll function: Converts a string to a long long type variable Atof function: Converting a string to a double type variable The conversion process of these functions is to take the readable part of a string into the variable An unreadable portion is encountered and the
