I'm looking at prices of low-capitalization crypto meme coins. I want to format and show as a decimal in the print statement, up about 10 digits. For example, the price of Saitama as shown on CoinGekco is $0.000000100861.
I don't understand if I'm using the Decimal library wrong, or if this is just a print/formatting issue.
from decimal import Decimal
# I think everything after the 7663 is irrelevant, this is a number I'm getting back
# from a Uniswap API. It could be the price in ETH, that is my next issue.
price_float = 2.08229530000000007663121204885725199461299350645049344166181981563568115234375E-11
price_decimal = Decimal(str(price_float))
print("float:", price_float)
print("decimal:", price_decimal)
Results:
float: 2.0822953e-11
decimal: 2.0822953E-11
Desired Results:
float: 2.0822953e-11
decimal: .000000000020822953
But if I try an exponent less than 6 it seems to work:
price_float = 2.08229530000000007663121204885725199461299350645049344166181981563568115234375E-6
Result:
decimal: 0.0000020822953000000003
You are probably looking for something like print("{:12.10f}".format(price_decimal))
. The output format is not controlled here by the decimal library
I do that
print(f'{price_float:.20f}')
print(f'{price_float:.20E}')
Output
0.00000000002082295300
2.08229530000000007663E-11
