WebMar 28, 2016 · Precision of int and float Data Types¶. Most programming languages define the range of values that can be stored in a specific data type. For example, an “int” in Java can store values in the range -2,147,483,648(-2 31) to 2,147,483,647 (2 31-1).GLSL let’s you pick from three different precision levels for the basic data types.

WebIn some situations, an expression and its type will be implicitly converted to a different type. The spec shows all possible implicit conversions inside a table, also int -> float. It further says: When an implicit conversion is done, it is the same conversion that would be done under explicit conversion, using a constructor. e.g. float a = 1; cuanto equivale un m3 a litrosWeb6.3.1 Basic Types.
