How to reclassify in Rastercalc?

Question

I now need to reclassify, I'm using rastercalc... but I can't get the syntax right!!

I need that values >0 become 1

I found this example... eq( [relief]@1, [mask]@4, 150 )

so I tried: ( [raster A insularis_1]@1, > 0, 1) and I absolutely failed

Answer 1

You simply need to use following expression

raster A insularis_1@1 > 0

The expression means , set all values greater than 0 as 1 and others as 0.
