You can use sscanf also. For example:

float fp = 0; sscanf( text, "%f", &fp );

To convert back use sprintf()

One should check sscanf's return value to make sure it successfully converted the string into a float, too.

Use atoi()/strtol() and atof()/strtod() library functions to convert from string.

To convert back use sprintf() with %d and %f format specifiers.

Take a look at sscanf() and sprintf().
