Function Documentation

uint32_t castFloatBytesToInt

(

float

f

)

Cast the in-memory representation of the given float directly to an int.

This is useful for printing the hex representation of a float number (which is considerably cheaper than a full decimal float formatter, in both code size and output length).

uint32_t zigzagEncode

(

int32_t

value

)

ZigZag encoding maps all values of a signed integer into those of an unsigned integer in such a way that numbers of small absolute value correspond to small integers in the result.

(Compared to just casting a signed to an unsigned which creates huge resulting numbers for small negative integers).
