float data precision and fat16 lib

when trying write value of float variables sd card using write function of fat16 lib, precision of float values reason limited 2 digits.

does know how possible write float values 7 digits precision using fat16 lib.

thanks help.

as string, instead?

code: [select]

float somevalue = 0.002;
char stringvalue[12];
sprintf(stringvalue, "%.7f", somevalue);

then, write stringvalue sd card, instead of somevalue;
