stringtodouble not work
faustf:
hi guys i have this script
in this part of code i have this array ObjectSetText(ts+IntegerToString(line), StringSubstr(TS[line,1], 10, 0) +" "+ TS[line,3] +" "+ TS[line,4],10, "Courier");
TS[line,3] inside of them i have a price , i want normilize a double because in file csv some time i have a price without a zero after dot 1.5 and i want 1.50000
i create a code like this normalizedouble (StringoTouble(TS[line,3]),5) , but not print nothing , how is possible to do that ?
thankz
show your code with StringToDouble function.
