How to evaluate a string of numbers in the same command of AWK
Hi,
I am trying to do evaluate one numerical string after substitution.
++++++++++++++++==
What I have = "7.04+2.3Xlog(0.72e-6X1.0e6)X1.9596"
What I need = evaluate 7.04+2.3*log(0.72e-6*1.0e6)*1.9596 = 5.55941
what I am doing;
here intention is to replace all "X" with "*" and then evaluate the string of numbers and print the evaluated value which I am unable to achieve. Please help

Hi,
I am trying to perform a simple soustraction between two floating numbers and cannot get it done for some reason due to the use of the sub command.
The following is the straight-forward result of the soustraction:

Hello,
I have this:
#!/usr/bin/ksh
V1=ABC
str="hello 123;${V1}"
eval "echo $str"
i get
hello 123
/script.sh ABC not found
However eval works if $str variable doesn't contain a semicolumn (eg if str="hello 123~${v1}"
running the eval statement above would produce (2 Replies)

glevalpoint1
GLEVALPOINT(3G)GLEVALPOINT(3G)NAME
glEvalPoint1, glEvalPoint2 - generate and evaluate a single point in a mesh
C SPECIFICATION
void glEvalPoint1( GLint i )
void glEvalPoint2( GLint i,
GLint j )
PARAMETERS
i Specifies the integer value for grid domain variable i.
j Specifies the integer value for grid domain variable j (glEvalPoint2 only).
DESCRIPTION
glMapGrid and glEvalMesh are used in tandem to efficiently generate and evaluate a series of evenly spaced map domain values. glEvalPoint
can be used to evaluate a single grid point in the same gridspace that is traversed by glEvalMesh. Calling glEvalPoint1 is equivalent to
calling
glEvalCoord1( i./u+u1 );
where
/u=(u2-u1)/n
and n, u1, and u2 are the arguments to the most recent glMapGrid1 command. The one absolute numeric requirement is that if i=n, then the
value computed from i./u+u1 is exactly u2.
In the two-dimensional case, glEvalPoint2, let
/u=(u2-u1)/n
/v=(v2-v1)/m,
where n, u1, u2, m, v1, and v2 are the arguments to the most recent glMapGrid2 command. Then the glEvalPoint2 command is equivalent to
calling
glEvalCoord2( i./u+u1, j./v+v1 );
The only absolute numeric requirements are that if i=n, then the value computed from i./u+u1 is exactly u2, and if j=m, then the value
computed from i./v+v1 is exactly v2.
