Decimal values
The ParsiQL abstraction to work with decimal values of arbitrary precision and scale
Decimal value type
Only non-negative decimal values are supported at this moment
It is possible to represent some decimal value (i.e. 123.45678) in ParsiQL with a special (struct) type:
1
{
2
value: int256,
3
decimals: int256
4
}

For example,
1
...
2
let sampleDecimal = {value: 12345678, decimals: 5} # Represents 123.45678

We have introduced important (operator) functions to perform decimal value calculations.
Addition
The function
add(decimalValueA, decimalValueB) takes 2 decimal values as an argument and returns their sum.Details
Parameters
decimalValueA: {value: int256, decimals: int256}; the first decimal valuedecimalValueB: {value: int256, decimals: int256}; the second decimal valueOutput
{value: int256,decimals: int256}; the resulting decimal valueExample
1
...
2
let decimalValueA = {value: 5, decimals: 0} # 5
3
let decimalValueB = {value: 12, decimals: 1} # 1.2
4
​
5
let result = add(decimalValueA, decimalValueB}
6
​
7
# result is {value: 62, decimals: 1} (6.2)

If at the moment of Smart-Trigger execution the
result would be equal to {value: 62, decimals: 1} which represents 6.2Comparison
The function
compare(decimalValueA, decimalValueB) takes 2 decimal values as an argument and returns 1ifdecimalValueAis strictly greater thandecimalValueB0ifdecimalValueAis equal todecimalValueB-1ifdecimalValueAis strictly less thandecimalValueB

Parameters
decimalValueA: {value: int256, decimals: int256}; the first decimal valuedecimalValueB: {value: int256, decimals: int256}; the second decimal valueOutput
integer; the resulting decimal value that can be either 1, 0 or -1Example

if result == 1 then
8
# Evaluates to "true", because result is "1", since 5 > 1.2

If at the moment of Smart-Trigger execution the
result would be equal to 1, since 5 is greater than 1.2.Last modified 1yr ago
