Zorro S 2.37.4b

Code

function run()
{
    asset("EUR/USD");
    AssetFloat[0]=1234.56;
    printf("\n%s = %f",Asset,AssetFloat[0]);
    quit("ok!");
}

have output:

Code


testIN compiling...........
EUR/USD = 0.000000
Test: testIN EUR/USD 2016..2021

Other problem - must be know

Code


function run()
{

    asset("EUR/USD");
    AssetVar[0]=33.99;
    printf("\n%s = %f",Asset,AssetVar[0]);
    AssetFloat[0]=1234.56;
    printf("\n%s = %f",Asset,AssetVar[0]);
    quit("ok!");
}

have this output:

Code


testIN compiling...........
EUR/USD = 33.990002
EUR/USD = 33.989998
Test: testIN EUR/USD 2016..2021
Assets Assets4

ok!

This is correct - from manual:
32 general purpose int or float variables for internally storing integers or floats specific to the current asset. They are shared with AssetVar/AssetStr at twice the index, i.e. AssetVar[N] is shared with AssetInt[2*N] and AssetInt[2*N+1]. They cannot be read from the asset list. AssetInt can also be used to store asset-specific series or pointers for using them in a tmf or tick function.

You need to cast float to var in order for printf to work.

Yes, var(double) is double the width of float. This has implications for pointer arithmetic / array positions.

You can read var and strings up to seven characters in length in your asset list for AssetVar and AssetStr, respectively.
