#23 – Real Literals
July 10, 2010 Leave a comment
There are several ways to indicate real number (floating point) literals in C#. Real literals are assumed to be of type double, but may also be of type float or decimal, depending on the suffix included with the literal.
Suffix / type:
- f – float
- d – double
- m – decimal
Here are some examples:
// Suffixes double d1 = 1.0; // ok object o1 = 1.0; // Also double float f1 = 3f; // float float f2 = 1.0f; // Must have 'f' suffix for float double d2 = 1.0d; // Optional 'd' suffix decimal d3 = 1.0m; // Exponents double d4 = 1.2E3; // 1200 double d5 = 1.2E+3; // 1200 double d6 = 1.2E-3; // 0.0012 double d7 = 2E3; // 2000 double d8 = 2E-3; // 0.002 float f3 = 2E-3f; decimal d9 = 2E-3m;
