How do you cut off decimals?
To get rid of all decimal places without regard to their value, use the INT() function (short for integer). This function takes one argument, the value, and returns whatever is to the left of the decimal point. To get rid of some decimal places without and rounding, use TRUNC(), which is short of truncate.

Can Java int has decimal?
Numbers are so important in Java that six of the eight primitive data types are numeric types. There are both integer and floating point primitive types. Integer types have no fractional part; floating point types have a fractional part. On paper, integers have no decimal point, and floating point types do.
What are decimals called in Java?
Floating point numbers are also called floating point literals in Java. For calculations using decimal values, Java supports two basic data types: float and double. Together, these support decimal or floating point numbers in the Java programming language.
