As a decimal fraction, yes.
In C float a[8]; In Java float a[] = new float[8];
#include<io.sys> // Temperature conversion functions: float celcius_to_fahrenheit (double c) { return c * 9.0 / 5.0 + 32.0; } float celcius_to_kelvin (double c) { return c + 273.150; } float fahrenheit_to_celsius (double f) { return (f - 32.0) * 5.0 / 9.0; } float fahrenheit_to_kelvin (double f) { return celsius_to_kelvin (fahrenheit_to_celsius (f)); float kelvin_to_celsius (double k) { return k - 273.150; } float kelvin_to_fahrenheit (double k) { return celsius_to_fahrenheit ( kelvin_to_celsius (k)); int main (void) { double c, f; scanf ("Enter a temperature in Celsius: %f", c); printf ("%f Celsius is equal to %f Fahrenheit\n", c, celcius_to_fahrenheit (c)); return 0; }
There are mainly 3 types of variables in c. Integer, Float and character :)
What's your problem with that? It's a (quasi-)standard value for a 'float'.
casting a value is when the data type is changed from one type to another.int a = 100;float b:b = (float)a;------The (float)a casts an int to a float. In C this is automatic but in C++ it is not. For the sake of readability and debugging it is a good idea to put the cast in the code, this is relay helpful 6 months later when you review your work.
float percent = ((float)CurrentItems / (float)MaxItems);
In C float a[8]; In Java float a[] = new float[8];
10.444444 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its rational equivalent is 10444444/1000000 which can be simplified, if required.
A fraction of 360 degrees
Rational, since it can be displayed as a fraction. In this case, -5,501/100.
#include<io.sys> // Temperature conversion functions: float celcius_to_fahrenheit (double c) { return c * 9.0 / 5.0 + 32.0; } float celcius_to_kelvin (double c) { return c + 273.150; } float fahrenheit_to_celsius (double f) { return (f - 32.0) * 5.0 / 9.0; } float fahrenheit_to_kelvin (double f) { return celsius_to_kelvin (fahrenheit_to_celsius (f)); float kelvin_to_celsius (double k) { return k - 273.150; } float kelvin_to_fahrenheit (double k) { return celsius_to_fahrenheit ( kelvin_to_celsius (k)); int main (void) { double c, f; scanf ("Enter a temperature in Celsius: %f", c); printf ("%f Celsius is equal to %f Fahrenheit\n", c, celcius_to_fahrenheit (c)); return 0; }
If you have a mixed fraction a b/c, the improper fraction is (a*c + b)/c. I'll let you figure out this particular problem on your own. :)
2.14= 2 14/100 = 2 7/50
The mixed number ab/c is equivalent to the improper fraction (a*c+b)/c
Float
The C language does not provide any support for graphics as standard. C is designed to be as generic as possible, but graphics are a system-specific feature. To use graphics in C you need a third-party graphics library that supports your operating system and hardware, however generic libraries such as OpenGL are available. Nevertheless, it is not possible to draw curves, you can only approximate a curve using a series of short lines. The shorter the lines and the higher the resolution, the smoother the curve will appear. Assuming you have access to an OpenGL library, you can draw an ellipse as follows: void DrawEllipse(float cx, float cy, float rx, float ry, int num_segments) { const float pi = atan (1) * 4; float theta = 2 * pi / float (num_segments); float c = cosf (theta); float s = sinf (theta); float x = 1; float y = 0; float t; glBegin (GL_LINE_LOOP); for (int i = 0; i < num_segments; ++i) { glVertex2 f (x * rx + cx, y * ry + cy); t = x; x = c * x - s * y; y = s * t + c * y; } glEnd(); }
It is C/1.
