14. Single & double Precision coderanch.comHi, Sunanda! The single and double precision refer to the IEEE 754-1985 standard. For Java the following is true: single prec -> 32 bits -> Min = 1.43e-45 -> Max = 3.4e38 Double prec -> 64 bits -> Min = 4.942-324 -> Max = 1.8e308 As you can see, double precision can hold much larger values then the single precision. You ... |
