SUMMARY
When starting a new (bank) account with initial balance = 0.00, and entering a few operations, the percent of change calculation in dashboard widgets shows an insane long number (probably some kind of max of data type, or so). 

STEPS TO REPRODUCE
1. create a new account, initial balance = 0.00
2. add some operations
3. check the operations
4. open the default dashboard

OBSERVED RESULT
The "accounts (full)" and "banks (full)" widgets show an insane number for the first month of percent increase. (+1,000,000,000,000,000,052,504,760,255,204,420,248,704,468,581,108,159,154,915,854,115,511,802,457,988,908,195,786,371,375,080,447,864,043,704,443,832,883,878,176,942,523,235,360,430,575,644,792,184,786,706,982,848,387,200,926,575,803,737,830,233,794,788,090,059,368,953,234,970,799,945,081,119,038,967,640,880,074,652,742,780,142,494,579,258,788,820,056,842,838,115,669,472,196,386,865,459,400,540,160.00 %)

EXPECTED RESULT
not sure, maybe no percentage calculation for the first month when initial balance is zero? I guess anything other than this huge number taking a lot of space...
