Description
Hi! Please, help with float serialization.
Function to cut one decimal and part of code:
`
float Round1(float tmp) {
return ((int)(tmp * 10)) / 10.0;
}
DynamicJsonBuffer jsonBuffer(200);
JsonObject& log = jsonBuffer.createObject();
tmp_t=24.35141; // float value from sensor
log["dht_t"] = Round1(tmp_t); // cut to one decimal
`
got results in log file:
{"dht_t":24}
{"dht_t":24.1}
{"dht_t":24.2}
{"dht_t":24.29999} - for 24.3
{"dht_t":24.4}
{"dht_t":24.5}
{"dht_t":24.6}
{"dht_t":24.7}
{"dht_t":24.79999} - for 24.8
{"dht_t":24.9}
problem with x.3 and x.8
Any help are welcome!
