checking if a variable is either more(or less) than a positive and negative number

[Kamon145]

Hello everyone! I am currently working on a platformer and my player has a maximum run speed that i would like to keep them from going over, but other objects in the game (such as explosions, ect) should still be able to add speed, my current code as it stands is

spd[h] +=hinput*accel//add acceleration to speed either positive or negative depending on value returned
spd[h] = clamp(spd[h],-spd_max,spd_max)
x+=spd[h]

hinput returns either 1 or -1 depending on direction pressed,
this works for keeping the player from going over speed, but prevents additional speed from being added, i have tried something along the lines of adding a check at the beginning

if spd[h] != hinput*run_spd
spd[h] +=hinput*accel//add acceleration to speed either positive or negative depending on value returned
    spd[h] = clamp(spd[h],-spd_max,spd_max)

but this dosent work because i assume the exact value of spd_max is being skipped over, and I've tried using <= and >= and they both work, but only in one direction, is there a function to check if a number has gone past a value? like "if spd[h] is between -run_spd, and run_spd"?

The most basic form is this:

if (spd[h] >= -run_spd && spd[h] <= run_spd)

And because the range is in the form [-xxx, xxx] (i.e. symmetric around 0), this special form can also be used:

if (abs(spd[h]) <= run_spd)
