Hello Everyone,
Today I am sharing a simple math expression parser that I made. This parser can parse and evaluate math expressions.
About the Parser
This parser supports many trigonometric functions and logarithmic and some general functions like exp, sqrt, abs etc. See the snapshots and everything will be clear. See the third screen shots for examples and their output

Description :
This parser is a simple math expression parser that
parses and evaluates various mathematical functions.
Triginometric functions : sin, cos, tan, arctan, arccos,arcsin, sec, cosec,cot
Logarithms : ln is used for natural log, log10 is log base 10 and log2 is log base 2
Other functions : exp for exponentiation, abs for absolute value, sqrt for square root
Numbers like 45.3e-13 are also supported
This parser can also take functions of one variable like
a math relation log10(x*sin(30*x)) with a variable x. Whenever such
expressions are encountered you are asked to enter the value of x.
Please Note :
- Trigonometric functions work with radians and not degrees
- sin x is not valid but sin(x) or sin (x) is valid. Similarly its true for others too
- This parser also skips whitespaces and so it will work as long as parenthesis are in correct order
Type help, description, usage for assistence and exit to leave.
Usage : Type any mathematical expression with the functions stated above in the description
example : sin(2*x)*cos(x)
