fstore : store float in local variable : index : visitVarInsn()

Description

Pops a single-precision float off the stack and stores it in local variable <varnum>. The fstore instruction takes a single parameter, <varnum>, an unsigned integer which indicates which local variable is used. <varnum> must be a valid local variable number in the current frame.

Example

fconst_2        ; push 2.0 onto the stack
fstore 3        ; pop 2.0 off of the stack and store it in local variable 3
