Well, I searched for some time on the Internet for an reliable way to convert from a floating point to String, but I found none in 10 secconds and did my self that.

If you need, this is the code (Also explained a bit):

Code: [Select]
`String floatToString(float f, int decimals = 2){ /* Transforms the floating point string process: eg.: using decimals = 2, input: 1.23456 1.23456 * (pow(10, 2+1) 1.23456 * 1000 = 1234 (as a long) now, let's move digits asside: 3 goes to 4, 2 goes to 3. Stages: "1234" "1233" "1223" Not, put a dot in the place of the separator "1.23" */ long fLong = f*(pow(10,decimals+1)); String longString = String(fLong); int len = longString.length(); for(int i = 0; i < decimals; i++){ longString[len - 1 - i] = longString[len - 2 - i]; } longString[len - decimals - 1] = '.'; return longString;}`
