amath(1) General Commands Manual amath(1) NAME amath - Simple command line calculator SYNOPSIS [ --noansi ] [ --shell | expression ] DESCRIPTION amath features a case sensitive command line interface, internal IEEE 754 calculations with 15 significant digits, calculations with real and complex numbers, variables and user defined functions, logarithmic and exponential functions, trigonometric and hyperbolic function and se- lected mathematical constants and rounding functions. OPTIONS --noansi Disable output of ANSI escape codes. Default is enable. --shell Open an interactive shell.

EXAMPLES Add two numbers: $ amath 1.3 + 2.6 Find cosine of pi/2: $ amath "cos(pi/2)" Find square root of minus 25: $ amath "sqrt(-25)" Show only 5 digits in the result of a division: $ amath "digits 5;34/11" Script block with functions: round(1.5461);round(-1.5461); ceil(43.5461);ceil(-43.5461); floor(39.9531);floor(-39.9531); trunc(23.827);trunc(-23.827); sqrt(100);sqrt(52.23); Script block with user defined functions: f(x)=x*2+1; g(y)=y^2+y*1.5+2; a=2;b=3;c=a+b; f(2.2);c+1.1; BUGS • If amath is linked with system libraries (-lm) sometimes the real part of a result of arccosh of a complex number, is negative instead of positive. • coth() with complex numbers is inaccurate on the 14th digit.
