USAGE: floatexpr [] [| ..]
evaluates expressions and writes result to stdout.
is either a floating point number OR the name of a textfile,
containing a floating point number, optionally preceded by
a string of letters and/or underscore(s).
If this is not the last but the file does not exist
and a default value is defined, that value is used instead.
After "-prefix" and "-suffix" is interpreted as a literal string.
FUNCTION:
-add sum of s. Default: 0.
-count number of s. Must be first and only function.
-cosr cos() of in radians.
-cosd cos() of in degrees.
-cosg cos() of in grads.
-diff sum of all but last s, minus last . Default: 0.
-div divide by last . Default: 1.
-exp =exp(). Default: 1.
-exp2 =2^. Default: 1.
-exp10 =10^. Default: 1.
-harm write series. Must be first and only function.
-int result rounded off to nearest integer value.
-ln =ln(). Default: 0.
-log10 =10log(). Default: 0.
-log2 =2log(). Default: 0.
-mean mean value of s. Default: 0.
-mul product of s. Default: 1.
-muldiv product of all but last s, divided by last . Default: 1.
-prefix insert before result.
-rms root mean square of s. Default: 0.
-series write series. Must be first and only function.
-sinr sin() of in radians.
-sind sin() of in degrees.
-sing sin() of in grads.
-sqrt square root of absolute value of result.
-sub sum of all but last s, minus last . Default: 0.
-suffix append after result.
-sum sum of s. Default: 0.
-sumdiv sum of all but last s, divided by last . Default: 1.
-tanr tan() of in radians.
-tand tan() of in degrees.
-tang tan() of in grads.
NOTES: the last can also be the result of a .
-prefix and -suffix should not be the last function.
FORMAT:
-d write result with digit mantissa, no mantissa for integer values.
-f always write result with digit mantissa.
-z write rounded off result preceded by zeros in symbols.
-. always write result in symbols with digit mantissa.
Default: -12d .
On inability to read a number or open a file no output is written to stdout.
Error messages are written to stderr.
