/** \fn SkFloatToDecimal
Convert a float into a decimal string.
The resulting string will be in the form `[-]?([0-9]*\.)?[0-9]+` (It does
not use scientific notation.) and `sscanf(output, "%f", &x)` will return
the original value if the value is finite. This function accepts all
possible input values.
INFINITY and -INFINITY are rounded to FLT_MAX and -FLT_MAX.
NAN values are converted to 0.
This function will always add a terminating '\0' to the output.
@param value Any floating-point number
@param output The buffer to write the string into. Must be non-null.
@return strlen(output)
unsigned SkFloatToDecimal(float value, char output[kMaximumSkFloatToDecimalLength]);
