__attribute__()

void __attribute__

(

(noinline)

)

Convert the given fixedpt number to a decimal string.

The max_dec argument specifies how many decimal digits to the right of the decimal point to generate. If set to -1, the "default" number of decimal digits will be used (2 for 32-bit fixedpt width, 10 for 64-bit fixedpt width); If set to -2, "all" of the digits will be returned, meaning there will be invalid, bogus digits outside the specified precisions.
