```pcss
|
|
.foo {
|
|
top: calc(1px * pow(2, 3));
|
|
line-height: sqrt(1.2);
|
|
padding: hypot(3px, 4px);
|
|
order: log(10, 10);
|
|
min-height: calc(e - exp(1));
|
|
}
|
|
|
|
/* becomes */
|

|
|
|
```js
|
|
postcssExponentialFunctions({ preserve: true })
|
|
```
|
|
|
|
```pcss
|
|
.foo {
|
|
top: calc(1px * pow(2, 3));
|
|
line-height: sqrt(1.2);
|
|
padding: hypot(3px, 4px);
|
|
order: log(10, 10);
|
|
min-height: calc(e - exp(1));
|
