of all formats (integers, longs, floats, and so on) to strings and vice
versa
The following functions can be used to convert integers to
strings:

itoa() Converts an integer value to a string.

ultoa() Converts an unsigned long integer value to a string.
The following functions can be used to convert floating-point values to
strings:

ecvt() Converts a double-precision floating-point value to a string
without an embedded decimal point.
fcvt() Same as ecvt(), but forces the precision to a specified number of
digits.
