Get input float from Math.cos() output value

it helps some times cos is not injective, so you cannot tell (precisely) what the original input was. For example, cos(0) = cos(2π) = 1. You can however use the Math#acos method to identify a possible input.

Convert time input to a float to enable math functions in C++

it fixes the issue As soon as one of the values is double, then the arithmetic will be done in double, with double results. So you can convert the minutes to double, using any of the three C++ syntaxes: static_cast(minutes), double(minutes) or (double)minutes, or just divide by 60.0, rather than the integer 60. (I like to be explicit, so I'd write double(minutes) / 60.0. And some people prefer static_cast, even in this case.)
With regards to the validation, I'd do it before conversion; once you've added the minutes to the hours, it's too late anyway.

hope this fix your issue The user inputs their age, and I have to return that age and then half of the age number in a decimal value, as well as displaying an inputted salary in dollar amounts. , use the string format options:
code :
Console.WriteLine("Your age is {0}, and half your age is {1:00.00}."
        , x, result);

wish help you to fix your issue Matlab's symbolic math toolbox contains a function called double.

Printing math with user input: Can't convert float to str implicitly

wish help you to fix your issue As the error message states: You have to convert 'float' to str explicitly.
This fixes your problem:
code :
print("Injectable SSH "+ str(result2) + " for the Network " + str(num2))
print("Injectable SSH {} for the Network {}".format(result2, num2))

Convert a Math Equation to output as a float value

will help you In C# the result of dividing 2 integers is an integer. If you want it a float then cast one of them into a float:
code :
var maths = anInteger / (float)keyprice;
textBox1.Text = $"{textBox1.Text} Converted into: {maths.ToString("n2")}";
var maths = anInteger / (float)keyprice;
textBox1.Text = textBox1.Text + "Converted into: " + maths.ToString("n2");
