Error and significant figures when rounding?

Homework Statement

So I'm determining the specific heat capacity of brass for a lab report, when i initially measured temperature it was to two significant figures (this was the measurement with the least significant figures)

My final answer, remarkably was 0.38 (j/g*K) but my error was 0.0235 so i rounded that to two significant figures, however doing that i get an answer of 0.38±0.024. This means that my highest and lowest measured value would be to three significant figures (0.38-0.024=0.356 (j/g*K)) see my problem?

The Attempt at a Solution

Should i round the error to the hundredths place or should i just leave my error as it is?

You think it correctly, the error has to be rounded to 0.02.
