did not check whether the amount is real about ocore HOT 3 OPEN

issue code:
if (amount){
if (typeof amount !== 'number')
throw Error('amount must be a number');
if (amount < 0)
throw Error('amount must be positive');
}

from ocore.

Such a try should result on a validation error at this point of code:
https://github.com/byteball/ocore/blob/master/composer.js#L651
with something like Validation error: amount must be positive integer, found 996741.7 returned as error.
It's before broadcasting or writing into database so I don't understand the consequences you are talking about.
It should be appropriate though to add a check for integer directly in sendMultiPayment function.

All amounts are integer, in the smallest unit (bytes). There is no decimals.
