This tool provides you with the capacity to do simple mathematical calculations to a high degree of accuracy, which in turn is determined by the precision parameter that specifies the minimum number of significant digits displayed.
The square root operator is unary, requiring only one argument. The remaining operators are binary, thus they require two arguments. For example, in the multiplication 5*2=10, 5 and 2 are arguments, * is the multiplication operator, and 10 is the result displayed to two significant figures.
If you have a chain of operations to perform, you could copy the results and paste it to a new expression for additional calculations.
Built-in constants:
Two are available: pi (3.141592653589...) is accurate to 4000 digits. (Click here to see π to 10,000 digits), while e (2,718281828...) is accurate to 100 digits only. You can enter these values as arguments.
The operators available are:
| operator | remarks |
|---|---|
| + | Addition, arg1+arg2 |
| - | Subtraction, arg1-arg2 |
| * | Multiplication, arg1*arg2 |
| / | Division, arg1/arg2 |
| s | Square Root, sqrt(arg1), (only first argument used) |
| p | power, arg1**arg2 |
| m | modulo, arg1 mod arg2 |
| h | HCF, Highest Common Factor(arg1, arg2) |
| l | LCM, Lowest Common Multiple(arg1, arg2) |
