It is commonly known simply as double. In general a double has 15 decimal digits of precision, while float has 7. 0, it should be printed as 12 only. Hence, double can handle much bigger fractional numbers than float. but if you only want to calculate down to the second digit (for monetary purposes for example) use an integer (as if you are using cents as unit) and add some scaling logic when you are multiplying/dividing Aug 6, 2012 · If you were to replace that with java. For example this java code: float a = 1. For example 33554435 (or 0x200003) will be truncated to around 33554432 +/- 4. Precision is the main difference where float is a single precision (32 bit) floating point data type, double is a double precision (64 bit) floating point data type and decimal is a 128-bit floating point data type. Data types are divided into two groups: Primitive data types - includes byte, short, int, long, float, double, boolean and char.
