“atof” function: In C++, the predefined function “atof” is used to convert a string value into a double-precision floating point value; it passes a string literal or character array as an argument and it converts the received value into a double type value; it takes only one parameter as an argument. If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting. In same way, the function will return “0” when the values can’t be able to convert into double data type. Syntax: Syntax for the “atof” function is as follows: double atof (const char* n); In the above statement, “double” represents the return type of the function. “atof” represents the name of the function. “const char*” represents the data type of the passing argument. “n” is a string variable which is required to be converted. Example: The example for the “atof” function is as follows: //change the string literal to a double value. double n = atof ("1258.11E-14 "); In the above line, the string literal “1258.11E-14” is passed as an argument to “atof” and it returns the converted value that is “1.25811e-11”.

“atof” function:

In C++, the predefined function “atof” is used to convert a string value into a double-precision floating point value; it passes a string literal or character array as an argument and it converts the received value into a double type value; it takes only one parameter as an argument.

If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting.

In same way, the function will return “0” when the values can’t be able to convert into double data type.

Syntax:

Syntax for the “atof” function is as follows:

double atof (const char* n);

In the above statement,

“double” represents the return type of the function.

“atof” represents the name of the function.

“const char*” represents the data type of the passing argument.

“n” is a string variable which is required to be converted.

Example:

The example for the “atof” function is as follows:

//change the string literal to a double value.

double n = atof ("1258.11E-14 ");

In the above line, the string literal “1258.11E-14” is passed as an argument to “atof” and it returns the converted value that is “1.25811e-11”.
