use set_value plugin with floating-point values

Does the set_value plugin support floating-point values? All the examples provided by PDI website use integer numbers. https://pdi.dev/master/set_value_plugin.html

For example, I want to set the integer value of my_switch from an expression ${current_time} >= ${final_time} where current/final_time are floating-point numbers.

I got that the floating-point numbers are cast into integers before applying the >= operation.

For example, if current_time=1.0 and final_time=1.5, then my_switch=1 because [1.0]=1>=1=[1.5].

I also tried with ${current_time:f} >= ${final_time:f} but got the same wrong result.
