Calculator

Calculateur de base

This is a basic calculator with very simple graphical user interface.

User can calculate mathematical expressions using following built-in constants and functions:

pi = the ratio of the circumference of a circle to its diameter 3.14159265359

e = the base of the natural logarithms 2.71828182846

exp = returns e raised to the specified power

sqrt = returns the square root of a specified number

abs = returns the absolute value of a number

ln = returns the natural (base e) logarithm of a specified number

log = returns the logarithm of a specified number in a specified base

floor = returns the largest integer less than or equal to the specified number

ceiling = returns the smallest integral value that is greater than or equal to the number

round = rounds a value to the nearest integral value

sin = returns the sine of the specified angle

cos = returns the cosine of the specified angle

tan = returns the tangent of the specified angle

asin = returns the angle whose sine is the specified number

acos = returns the angle whose cosine is the specified number

atan = returns the angle whose tangent is the specified number

atan2 = returns the angle whose tangent is the quotient of two specified numbers

min = returns the smaller of two numbers

max = returns the larger of two numbers

pow = returns a specified number raised to the specified power

rnd = returns a random number from given value

npo2 = returns the next power of two value

cpo2 = returns the closest power of two value

ieeeremainder = returns the remainder resulting from the division of a specified number by another specified number

Examples how to use built-in functions:

sqrt ( pow ( 3, 5 ) )

sin ( pi * 3 / 4 )

rnd ( 5, 10 )

rnd (7)

ieeeremainder ( 9, 5 )

abs ( -5.2345)
