Decimal point showing error in Lua -

-

i'm using esplorer programming esp8266.

a = 7.5 print(a)

this lua code shows error "malformed number near '7.5' ". need add library or file?

which exact firmware (file) did flash esp?

i expect might have used 'integer' version, doesn't support floating point arithmetics, use 'float' firmware version instead.
