SpeedCrunch supports the following operators, listed in order of decreasing precedence: OperatorĮxponentiation Both variants are equivalent. We also distinguish unary operators (which act on a single number/operand) and binary operators (which link two operands). When writing an expression like 10+5*4, which operation will be executed first? The common rules of operator precedence tell us that in this case multipication shall be computed first, hence the result is 30. However, only about 78 significant digits are stored at any point. the part preceding the exponent) is required exactly one exponent must be specified.Ĭompared to most calculators, SpeedCrunch can accept very large numbers without overflowing (e.g. If the sign is ‘+’, you may simply omit it: e0, E10. So e+10, e-4, E-0 are all valid scale expressions. In addition, SpeedCrunch records all your calculations and place them in its history. When dealing with intense and complex calculation, this high precision ensures that you get less rounding errors in the end. ![]() The scale of a number (sometimes called its exponent) always begins with the scale character E or e followed by a signed integer. In term of precision, SpeedCrunch is able to hold up to 50 decimals of precision. Here, the e represents *10^, but it is considered a part of the number literal and treated with higher precedence. Naturally, in SpeedCrunch this could be written as 1.234*10^-9, but there’s also a shorthand notation: 1.234e-9. These are more commonly expressed in scientific notation for instance, 1.234*10 -9 is preferable to 0.000000001234. When dealing with very small or very large numbers (think the size of an atom or of a galaxy) the notation above is inconvenient.
