Here’s my code: x = 1.0 y = 100000.0 print x/y My quotient displays as 1.00000e-05. Is there any way to suppress scientific notation and make it display as...
I have a question about JUnit assertEquals to test double values. Reading the API doc I can see: @Deprecated public static void assertEquals(double expected, double actual) Deprecated. Use assertEquals(double...
I am trying hard to compare two floating point numbers within a Bash script. I have two variables, e.g. let num1=3.17648e-22 let num2=1.5 Now, I just want do a...
Today, I was looking through some C++ code (written by somebody else) and found this section: double someValue = ... if (someValue < std::numeric_limits<double>::epsilon() && someValue > -std::numeric_limits<double>::epsilon()) {...
A colleague of mine stumbled upon a method to floor float numbers using a bitwise or: var a = 13.6 | 0; //a == 13 We were talking about...
I need to format a float to “n”decimal places. was trying to BigDecimal, but the return value is not correct… public static float Redondear(float pNumero, int pCantidadDecimales) { //...
