2.3 Data Conversion

The data-conversion routines convert numbers to strings of ASCII characters and vice versa. These routines are implemented as functions, all of which are declared in the include file STDLIB.H. The atof function, which converts a string to a floating-point value, is also declared in MATH.H.
