Description

The list of methods to do Double to Long are organized into topic(s).

Method

longdoubleToRawLongBits(double d)
double To Raw Long Bits 
return Double.doubleToRawLongBits(d);
longdoubleToRawLongBits(double value)
Encode a double in a long. 
return Double.doubleToRawLongBits(value);
longdoubleToS390LongBits(double ieeeDouble)
Converts an IEEE double to an S390 double (as a long). 
long ieeeLongBits = Double.doubleToLongBits(ieeeDouble);
boolean positive = ((ieeeLongBits & DOUBLE_SIGN_MASK) == 0);
if ((ieeeLongBits & 0x7fffffffffffffffL) == 0) {
    return ieeeLongBits;
long exponent = ieeeLongBits & DOUBLE_EXPONENT_MASK;
exponent = exponent >>> 52;
exponent = exponent - DOUBLE_BIAS;
...
longdoubleToSortableLong(double val)
Converts a double value to a sortable signed long. 
return sortableDoubleBits(Double.doubleToLongBits(val));
longdoubleToSortableLong(double value)
Converts a sortable long to double. 
long bits = Double.doubleToRawLongBits(value);
return bits ^ (bits >> 63) & Long.MAX_VALUE;
