lesson 4 fund me and number conversion

[bonannogiovanni]

I really got stuck in lesson 4 "Remix fund me", so confusing the number conversion, 50*10e18 means that the require will fail if you send less than 50ethers so I had to remove three digits from that number to make it work by sending 0.51 ethers, don't understand why Patrick sends 0.02 and it passes thorugh...

its not 50 ether, its 50usd

[rishigarg256]

he did 0.02 because during the time of recording, the value of eth was 3000$, and min value to send is 50usd, so 3000*0.02=50

Ok, but why MINIMUM_USD equals 50*10E18?, Thats 50 billions of billion dollars!

@bonannogiovanni Because msg.value unit works in Wei that 10 to the power of 18 (means 18 zeros). That's why we are converting our 50 USD, so we can compare it with msg.value in the require statement.
