Please explain in English what this awk script is supposed to do. I can make a few wild guesses, but none of them make any sense to me.
Then note that awk uses double precision floating point arithmetic (which gives you about 15-17 significant digits on individual values). Rounding errors may significantly reduce the precision of your results depending on the ranges of values being multiplied and divided.
What does the data in input.dat look like?

I have a simple gnuplot question. I have a set of points (list of x,y,z values; irregularly spaced, i.e. no grid) that I want to plot. I want the plot to look like this:
- points in map view (no 3D view)
- color of each point should depend on its z-value.
- I want to define my own color scale

The model assumed for integers is binary representation (one's or two's complement), where the sign is represented by the value of the
high-order bit.
BITS(type) The number of bits in a specified type (for example, int).
HIBITS The value of a short integer with only the high-order bit set.
HIBITL The value of a long integer with only the high-order bit set.
HIBITI The value of a regular integer with only the high-order bit set.
MAXSHORT The maximum value of a signed short integer.
MAXLONG The maximum value of a signed long integer.
MAXINT The maximum value of a signed regular integer.
MAXFLOAT, LN_MAXFLOAT The maximum value of a single-precision floating-point number, and its natural logarithm.
MAXDOUBLE, LN_MAXDOUBLE The maximum value of a double-precision floating-point number, and its natural logarithm.
MINFLOAT, LN_MINFLOAT The minimum positive value of a single-precision floating-point number, and its natural logarithm.
MINDOUBLE, LN_MINDOUBLE The minimum positive value of a double-precision floating-point number, and its natural logarithm.
FSIGNIF The number of significant bits in the mantissa of a single-precision floating-point number.
DSIGNIF The number of significant bits in the mantissa of a double-precision floating-point number.
