What does -.60 mean in C language?

In C language, -.60 is a negative floating point constant that represents the value -0.60. It is expressed in double precision and can be used for various purposes such as calculations, mathematical operations, and data storage.

-.60 in C language

In C language, -.60 is a negative floating point number Constant, its value is -0.60. This means it is a decimal fraction with significant digits 0.60, preceded by a negative sign.

How to use -.60 in C code

-.60 constants can be used directly in C code, for example:

<code class="c">float x = -.60;</code>

This will Create a float type variable named x and initialize it to -0.60.

Precision

Although -.60 is a floating-point constant in C, it is expressed in double precision. This means it takes up 8 bytes in memory and has higher precision than the float type.

Compare with integers

-.60 Although it is a floating point constant, it can also be compared with integers. For example:

<code class="c">if (x == -60) {
  // ...
}</code>

This will execute the block of code when x equals -60. However, due to the inherent imprecision of floating-point arithmetic, it is not recommended to perform exact equality comparisons on floating-point constants.

Usage scenarios

-.60 constants are used in C code to represent negative decimal values. It can be used for various purposes such as calculations, mathematical operations, and data storage. For example, it can be used to calculate the circumference of a circle:

<code class="c">#define PI 3.14159265
float radius = 10.0;
float circumference = 2 * PI * radius;</code>

In this example, -.60 can be used to represent negative angle values, or for other purposes that require negative floating point constants.
