Question: How do I convert a floating-point number to a string?
Answer: Use function gcvt( ) to convert a floating-point number to a string. Following program demonstrates the use of this function.#include <stdlib.h> main( ) { char str[25] ; float no ; int dg = 5 ; /* significant digits */ no = 14.3216 ; gcvt ( no, dg, str ) ; printf ( "String: %sn", str ) ; } |
