Math

jq currently only has IEEE754 double-precision (64-bit) floating point number support.

Besides simple arithmetic operators such as +, jq also has most standard math functions from the C math library. C math functions that take a single input argument (e.g., sin()) are available as zero-argument jq functions. C math functions that take two input arguments (e.g., pow()) are available as two-argument jq functions that ignore .. C math functions that take three input arguments are available as three-argument jq functions that ignore ..

Availability of standard math functions depends on the availability of the corresponding math functions in your operating system and C math library. Unavailable math functions will be defined but will raise an error.
