[edit] FloatToInt(float)

Converts a number with a decimal into a number without one.

int FloatToInt(
    float fFloat
);

[edit] Parameters

float fFloat

• The float to convert to an integer.

[edit] Description

Convert fFloat into the nearest integer. Since an integer does not support precision (that is, decimal places), the precision is lost (truncated). No rounding of the number occurs.

[edit] Remarks

Marked incorrectly by BioWare documentation as rounding not truncating the decimal value. In other words, both of the floats 2.001 and 2.999 will be converted to the integer 2.

[edit] Example

// example courtesy of Ken Vargo
// normalizing angles
// variation of an example introduced by Vane
// when it was realized that FloatToInt acts like
// TRUNC() in MS Excel rather than INT().

int iAddAngles(int iAngleOne, int iAngleTwo);

void main()
{
    int iA1 = GetLocalInt (OBJECT_SELF, "a1");
    int iA2 = GetLocalInt (OBJECT_SELF, "a2");

    int iSum = iAddAngles(iA1, iA2);
    int iNegSum = iAddAngles( - iA1,  - iA2); 
    // this tests the negatives added together 
    //(-10 + -10 = -20 = 340 degrees)

    SendMessageToPC(GetFirstPC(), IntToString(iSum));
    SendMessageToPC(GetFirstPC(), IntToString(iNegSum));

    SetLocalInt(OBJECT_SELF, "a1",  iA1 + 10);
    SetLocalInt(OBJECT_SELF, "a2", iA2 + 10);
}

// this function return the normalized sum of two angles
// (will always be a positive angle value b/w 0 and 359).
int iAddAngles(int iAngleOne, int iAngleTwo)
{
    int iAngleSum = (iAngleOne + iAngleTwo);
    int iNormalAngleSum = iAngleSum - (360 * FloatToInt(iAngleSum/360.0));
    if (iNormalAngleSum >= )
    {
        return iNormalAngleSum;
    }
    else
    {
        return  360 + iNormalAngleSum;
    }
}
