Describe the bug Scanning a qrcode containing the amount in the URL puts the BTC value in the correct field but in the wrong format (exponential notation, e.g. 2.218E-5) instead of the decimal notation (e.g. 0.00002218).

To Reproduce Steps to reproduce the behavior:

1. Go to 'Send'
2. Click on 'Scan QR-Code Icon'
3. Scan the QR-Code
4. See error
5. Additionally after trying to send it anyway an error sows up: 'Amount can only contain numbers'

Expected behavior Show the value in decimal notation

Error message and wrong exponential notation in BTC amount field

Platform:

Additional context It occurs not only on Silent Payment addresses, also normal Bitcoin addresses are affected

[MrCyjaneK]

are you creating those qr codes in cake?

[gurkcity]

these qrcodes are created in PrestaShop software with a Bitcoin payment module https://www.onlineshop-module.de/zahlungsmodul-bitcoin-prestashop.html implemented the BIP0020 of the amount param, see https://en.bitcoin.it/wiki/BIP_0020#Simpler_syntax The silent payments here are still in a development process. Do you think, is there anything wrong with the QRcode?
