>> (1 + sqrt(5)) / 2 1.618033989
The value of a^b is raised to the power of .
>> 81^(1/2) 9
Most common elementary functions such as sqrt, exp, log, sin, cos, tan, asin, acos, and atan can be used in the expressions.
Complex numbers are supported directly. A complex number of real and imaginary parts a and b is displayed as a+bi, and can be entered as either a+bi, a+bI, a+bj, or a+bJ. For example
>> sqrt(-5) 0 + 2.236067977i >> (3+5i) / (2-3j) -0.6923076923 + 1.461538462i
If a constant has the M suffix, it is treated as a multi-precision floating point number. By default, it is stored with 128 binary digits. For example
>> (1 + sqrt(5M)) / 2 1.61803398874989484820458683436563E0
