Java Virtual Machine (Java Series)

fload

fload <varnum> or wide fload <varnum> In the first form, <varnum> is an unsigned integer in the range 0 to 0xFF. In the second (wide) form, <varnum> is an unsigned integer in the range 0 to 0xFFFF.

Stack

Pushes the float value held in a local variable onto the operand stack. The fload instruction takes a single parameter, <varnum>, an unsigned integer which indicates which local variable to retrieve. The single-word float held in that local variable is retrieved and placed on the stack. <varnum> must be a valid local variable number in the current frame.

Example

fconst_2 ; push 2.0 onto the stack fstore 1 ; pop 2.0 off of the stack and store in local variable 1 fload 1 ; push the value from local variable 1 (the value 2.0) ; back onto the stack Bytecode

For local variable numbers in the range 0-255, use:

iload, lload, aload, dload, wide
