Real constants and functions
You are encouraged to solve this task according to the task description, using any language you may know.
Show how to use the following math constants and functions in your language (if not available, note it):
- e (Euler's number)
- pi
- square root
- logarithm (any base allowed)
- exponential (ex)
- absolute value (a.k.a. "magnitude")
- floor (largest integer less than this number--not the same as truncate or int)
- ceiling (smallest integer greater than this number--not the same as round up)
BASIC
<qbasic>abs(x) 'absolute value sqr(x) 'square root exp(x) 'exponential log(x) 'natural logarithm 'floor, ceiling, e, and pi not available</qbasic>
Java
All of these functions are in Java's Math class which, does not require any imports: <java>Math.E; //e Math.PI; //pi Math.sqrt(x); //square root--cube root also available (cbrt) Math.log(x); //natural logarithm--log base 10 also available (log10) Math.exp(x); //exponential Math.abs(x); //absolute value Math.floor(x); //floor Math.ceil(x); //ceiling</java>
