Posted on by joaocsantos

Collect(colValores,{val: 84.7});
Collect(colValores,{val: 7.65});
Collect(colValores,{val: 7.65});
UpdateContext({locSum: Sum(colValores,val)})
//locsum = 100
//locsum > 100 returns true
//because locsum is in fact 100.0000000001
 
if i reverse the order of the collect to
 
Collect(colValores,{val: 7.65});
Collect(colValores,{val: 7.65});
Collect(colValores,{val: 84.7});
 
//locsum = 100
//locsum > 100 returns false

Unfortunately, floating point errors are quite common across many programming languages / platforms.

Since your values are all 2 decimal places or less, you could round the result to 2 places, which should fix the issue:

UpdateContext({locSum: Round(Sum(colValores,val),2)})

In some of these situations such as currency it may be better to work with integer values then convert them back.
