Precision for "price" float value when placing orders

[jdhurwitz]

What is the max precision for the "price" variable when placing an order, such as a limit order? I'm getting:

BinanceAPIException: APIError(code=-1111): Precision is over the maximum defined for this asset.

For the following float:
0.000614250470875

Is the trimming not handled by the API?

Hi @jdhurwitz no the API doesn't help you there at all.
Use the get_symbol_info function to get info about a particular symbol and then you can format your values for output using something like below

amount = 0.000614250470875
precision = 6
amount_str = "{:0.0{}f}".format(amount, precision)

I'm just going to leave this here...

The parameters ‘price’ and 'quantity' should be decimal, not float.
