Numbers

In Smalltalk numbers are objects of class NSNumber (9.2), but nevertheless, we can do calculation with them. The common operators acting on them are available.

Example:

nOne := 1.     " implicit creation "

nTwo := 3.75 * 28.

nThree := nOne - nTwo.

cosA := 33.0 cos.     " cosine of angle (degrees) "

phi := cosA acos.     " arccosine returns angle (radiants) "

Note: The operators must be surrounded with spaces. The interpreter will not correctly recognise them otherwise.

Other mathematical functions available: sin, asin, tan, atan, sqrt, exp, log.
