[SOLVED] Java conversion of Double.LongBitsToDouble

[Blaazen]

Hi, how would you convert this code to pascal?

Type "long" is Int64 (or QWord). "<<" is shl.

But what about Double.LongBitsToDouble?

Code: [Select]

public static double exp(double val) {
 final long tmp = (long) (1512775 * val + 1072632447);
 return Double.longBitsToDouble(tmp << 32);
 }
The code is fast exponential function - approximation of e^x.

This is my guess:

Code: [Select]

var
 i: int64;
 longBitsToDouble: double absolute i;
..
//return Double.longBitsToDouble(tmp << 32);
 i := tmp << 32;
 Result := longBitsToDouble;

Thanks, it works.
