Usage of datatypes in E1 Business Functions

Float/Math_Numeric
To a specific value:
MATH_NUMERIC an8mn = {0};
F0110 dsF0101 = {0};
int an8 =123;
IntToMathNumeric(an8,&an8mn);
MathCopy(&dsF0101.aban8,&an8mn);
Now the Math_Numeric field aban8 is set to 123 value;
T0 zero:
ZeroMathNumeric(&dsF0101.aban8);
Character/EVDT_CHAR
F986101 dsF986101={0};
dsF986101.OMDATM = _J('P');
