Floating Point Constants

[Constants]

説明

Similar to integer constants, floating point constants are used to make code more readable. Floating point constants are swapped at compile time for the value to which the expression evaluates.

n = 0.005;  // 0.005 is a floating point constant

Floating point constants can also be expressed in a variety of scientific notation. ‘E’ and ‘e’ are both accepted as valid exponent indicators.

10.010
2.34E52.34 * 10^5234000
67e-1267.0 * 10^-12.000000000067
